I bet the person who wrote this question has never even lifted a dumbbell in their life. Muscle fiber cross-sectional diameter, no doubt about it.

Option D? Really? I guess the muscle hydration state could play a role, but that seems like the least likely answer here.

Definitely option A! The increase in muscle fiber cross-sectional diameter is the primary reason for muscle growth in resistance training.

I'm not sure, but I think it could also be D) Hydration state of the muscle, as water content can affect muscle size.

I agree with Jackie, because when we lift weights, our muscle fibers get bigger.
