Question

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. A body - builder like Jason would have more muscle mass. Option B is incorrect as body - builders typically have less body fat. Option C is not the main reason for the weight difference. Option D is wrong because a lower body mass index would mean less weight (since \(BMI=\frac{weight}{height^{2}}\), with height being the same).

Answer:

A. Jason has more muscle mass than Ryan does.
