Which term best describes the number of calories the body uses at rest? ?

The choices can be found elsewhere and as follows:

body mass index
basal metabolic rate
resting heart rate
resting caloric count

I believe the correct answer is the second option. The term that describes the number of calories the body uses at rest would be basal metabolic rate. Hope this answers the question. Have a nice day.

Mars and earth have quite a few things in common. both are  terrestrial planets, both are located within the sun’s  habitable zone, both have  polar ice caps, similarly  tilted axes, and similar  variations in temperature. and according to some of the latest scientific data obtained by rovers and atmospheric probes, it is now known that mars once had a  dense atmosphere  and was covered with  warm, flowing water.
