Which of the following activities is likely to have the least daily energy expenditure?

Thermic activity refers to the energy expenditure associated with the digestion, absorption, and metabolism of food. While this process does burn calories, it is generally less energy-intensive compared to physical activity, which includes any voluntary movement such as exercise and daily chores. Additionally, resting activities, which include simply sitting or engaging in light tasks, tend to use more energy than thermic activity because they often involve the body's baseline metabolic functions at a higher rate than just digesting food. Sleep activity, although it represents a low-energy state, is still associated with metabolic functions necessary for recovery and restoration. As such, thermic activity is likely to result in the least daily energy expenditure compared to physical activity, resting activities, and sleep activities. This makes it the correct choice in terms of relative energy cost.
