I've checked two of your wrong guesses. You're on your own now.

c. Not all mouse traps are designed to kill mice; some merely trap them.

The correct sentence is:

c. Not all mouse traps are designed to kill mice; some merely trap them.

Explanation:
To determine the correct sentence, we need to look at punctuation and capitalization. Option c is the correct choice because it uses proper punctuation. It uses a semicolon to join the two independent clauses ("Not all mouse traps are designed to kill mice" and "some merely trap them"). It also capitalizes the first letter of each sentence and uses the correct spelling of "mouse traps."
