defence for strategical player against 1.e4 opening
Check the opponent's games to see what they play as Black. A lot of people who play 1.e4 as White will hate the French Defence... it's exactly the kind of game they didn't want when they played 1.e4.
Also, they probably won't have seen it as much as 1. ... e5 and 1. ... c5, though they will have probably have seen it more than any other response.
P.S. Be prepared for the fact that unless White is used to the French, they are likely to respond with the Exchange Variation... because that gives exactly the kind of game that players of the French didn't want when they played 1. ... e6.

I cannot speak for all e4 players, but I love seeing the French Defense played against me. The Caro-Kann is a much better choice, but the best advice for the OP is to get better at tactics. I recommend playing the Sicilian to help encourage that, instead of trying to avoid it (which will only hamper the ability to improve).
The problem with the caro -khan is that it can still get you to very sharp games which is favourable to tactical players ( in some variations black can't even castle !!! )

I'm another voice for Caro-Kann, 1 e4 c6. I like it - and it's cousin the Slav, 1 d4 c6, because unlike the French or the Q's Gambit Declined, you (Black) are usually able to get your QB outside the pawn chain to f5 or g4 before e6 closes it in and makes it hard to activate.
Note that in ALL Defenses you have to make threatening tactical moves when you can: playing passively and defensively is an awful strategy. So base your strategic thinking on how you can gain equality after the opening and counter attack. In the Caro-Kann Advance Variation, which tends to be very closed, you usually have to think about attacking White's center Pawns with your c- or f-Pawn and you often have a N at d7 that supports that.
In all three of my current daily games where I have Black, I'm playing the Caro-Kann and they range from semi-open tactical to semi-closed positional games. You have to be ready for both, but most of the time the Caro-Kann is more positional.

What does it mean to be a strategical player?
If it means you're afraid of tactics, my first suggestion is to work on tactics!

Any opening can be tactical, or strategical. Learn how to deal with both, instead of avoiding one or the other.
Thanks for the recommendations....I think i should play some tactical type openings... . U know, For a change of taste..
Any advices on tactical openings for my level ( i play 1500 on rapid )
( Also ,Recommendations for choosing certain Sicilian lines will be helpful )

sreeragkkhd, as most of the people have been pointing out, you can't avoid tactics if you play chess.
I recommend that most players of your strength start out by learning the classical means of development first. That means playing 1.e4 or 1.d4 as White, and 1.e4 e5 and 1.d4 d5 as Black. Think of the Indian and Sicilian defenses as Calculus. Learn algebra first.

Play the Marshall Attack of Ruy Lopez
A line which gambits a pawn for a lovely attack on the kingside

Chess is a rich game. You might be itching for a King's Gambit Accepted but your opponent declines. So a balance of positional understanding and tactics will be useful.

BobbyTalparov,
Take a look at Greg Shahade's article on how to choose an opening repertoire. I agree completely with his article!
The point of recommending classical openings first isn't to limit the player, but to build a strong foundation. It's kinda like learning to play classical music before jumping into jazz.
BUT, it all depends on the goals of the chess player. If the main goal is to have fun, but not necessarily become the best player possible, then the opening repertoire doesn't need to be so structured.
And, I also recommend that a beginner play all sorts of stuff in casual games. I especially recommend playing gambits. A new player needs to learn quickly that material count isn't everything.
Anyway, take a look at the article below, which was published in Chess Life:
