Think about how you will turn the key once you insert it. There might be a trick to turning the key.

The shape of the end of key B will keep it from fitting into the keyhole.

The bit on the end of key C is too big to fit into the keyhole.

It's OK if you can't insert the key all the way until you've turned it. You may be able to insert a key and turn it partway before you insert it the rest of the way.
