select the correct answer.
jason is a body builder. despite being more fit, he weighs more than his brother ryan, who is the same height. which is the most likely reason for this?
a. jason has more muscle mass than ryan does.
b. jason has more body fat than ryan does.
c. jason has more water fluid mass than ryan does.
d. jason has a lower body mass index than ryan does.

Explanation:

Muscle is denser than fat. As a body - builder, Jason is likely to have more muscle mass. More muscle mass (since muscle is denser) would lead to a higher weight even at the same height. Option B is incorrect as a body - builder is less likely to have more body fat. Option C, having more water - fluid mass is not the most likely reason compared to muscle mass for a body - builder. Option D, body mass index (BMI=\(\frac{weight}{height^{2}}\)), if Jason weighs more (same height), his BMI would be higher, not lower.

Answer:

A. Jason has more muscle mass than Ryan does.
