,Question 1: What is the primary function of carbohydrates in the body?
• A) Provide energy
• B) Build muscle
• C) Aid in digestion
• D) Regulate body temperature
Correct Option: A) Provide energy
Rationale: Carbohydrates are the body's main source of energy. They are broken down
into glucose, which is used by the body's cells for fuel. While they also play a role in
digestion through fiber, their primary function is energy provision.
