Question

what is body composition?
○ how much of your body is made of fat and muscle
○ how much water is in your body
○ how much hair you have
○ how much you weigh

Explanation:

Body composition refers to the proportion of fat, muscle, bone, and other tissues in the body. The option "how much of your body is made of fat and muscle" directly relates to this definition. The other options (hair quantity, weight, water quantity) do not define body composition.

Answer:

A. how much of your body is made of fat and muscle (assuming the first option is A, adjusting the identifier based on standard multiple - choice numbering if needed, e.g., if the first option is 1., then 1. how much of your body is made of fat and muscle)
