B Correct answer
Explanation

Catabolism is the metabolic process that releases energy from food by breaking down complex molecules into simpler ones. During digestion and cellular respiration, large molecules like carbohydrates, fats, and proteins are broken down to release usable energy (ATP). Anabolism is the opposite - building up molecules. Basal metabolic rate is the total energy expenditure at rest, and the thermic effect of food is the energy cost of digestion.
