Basal metabolic rate increases with _______.

a. age c. a decrease in thyroid hormone
b. lean body mass d. all of the above

Reason for incorrect answer:

Option a. is given as, “age.”

In both males and females, BMR decreases with age. Thus, the increase in BMR is not related to the age of an individual. Hence, option a. is incorrect.
