Explanation:

Question 18 (What is the primary function of carbohydrates in the diet?)

Carbohydrates are the body's main source of energy. Building muscle is mainly from protein, aiding digestion is more related to fiber (a type of carb but not the primary function), and hydrating is water's role. So the primary function is providing energy.

Regular physical activity reduces chronic disease risk, improves mental health, increases energy, and builds muscle (reduced muscle mass is a negative, increased chronic disease risk is wrong). Among options, improved mental health is a known benefit.

Answer:

B) Providing energy
