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 bodybuilder like Jason, who is more fit, likely has more muscle mass. More muscle mass can lead to a higher weight even if body - fat percentage is lower. Body fat (Option B) would not make sense as a fitter person (Jason) would likely have less body fat. Water fluid (Option C) is not the main factor here. A lower body mass index (BMI) (Option D) for Jason (if he is fitter) would not explain a higher weight as BMI is weight/height². If height is the same (as they are brothers with same height implied), a higher weight would mean a higher BMI.

Answer:

A. Jason has more muscle mass than Ryan does
