You can also block the line of attack with another piece if possible.
Really dumb beginner question.

You can also block the line of attack with another piece if possible.
Thanks! Forgot to include that option as well.
Am I missing anything else?

A) Take the attacking piece (not possible in case of double check)
B) Shield your King with some piece or pawn of yours (not possible against Knight check or double check)
C) Move your King to a square free of check
If none of the above is available, it's check (and) mate.
Thanks. I really appreciate everyone's explanations.
Say I get the king in check. What are the king's options?
