c) Bf6 is met with a check, for example Qe6+. Bye bye mate in 2.
d) Bh7 is a check and is a forced mate in 2.
The problem is Bf6 isn't a check, so black gets to move.
So... black's going to attack's white's king. If it moves to the d file Qd5+ picks up the rook on h1.
If it moves to the f file Qe2+ is close to mate.
In any case it certainly isn't a mate in 2 anymore.
This is actually a good example for students. In tactics try to play the most forcing sequence. Sometimes (like here) it's the difference between a win and a loss.
Thanks wafflemaster. I don't know why I wasn't thinking to move the queen to put white in check. Usually it is not enough coffee, today I might have had too much. 
Appreciated.
yeah agreed. white has to force mate. Bf6 re8+ and black has the initiative and could even if nessicary sac the queen for the h rook with an easy win. but that is hardly nessicary
d)
I actually put the white king in the wrong place. It should have been on c1 but the answer would still be d).
