Explanation:

Muscle is denser than fat, so an athlete with more muscle mass (due to athletic training) can weigh more than a non - athletic person of the same height. Option B implies supplements artificially adding weight, which is less likely as supplements are for nutrition, not just weight gain. Option C: consuming extra calories doesn't necessarily mean weight gain if used for activity, and muscle mass is a key factor for athletes. So option A is the most logical.

Answer:

A. Kima has more muscle mass than her sister because she is more athletic.
