D. resting metabolic rate.

Explanation:

The Resting Metabolic Rate is the energy spent under conditions similar to basal energy expenditure that is defined as the minimum energy rate spent at 24 hours, corresponding to the energy spent to maintain the normal functioning of the body, such as breathing, blood circulation, blood body temperature, among others.

In this case, we can say that the number of calories needed to breathe, pump blood, grow hair and be alive is called the resting metabolic rate budget.
