A Correct answer
Explanation

This sentence is a first conditional, which uses the present simple in the if-clause ("if you can keep") and the future simple in the main clause ("I'll only tell you"). Option B incorrectly mixes "can" and "would", and Option C is semantically and grammatically incorrect.
