O Levels Biology (5090)•5090/11/O/N/19

Explanation
Energy needs from BMR and activity level Steps:
- Calculate basal metabolic rate (BMR) using Mifflin-St Jeor formula, assuming average height of 170 cm for comparison since not provided.
- Adjust BMR by activity multiplier: low activity (1.2), high activity (1.725).
- Compare total daily energy expenditure (TDEE = BMR × multiplier) across options.
- Identify highest TDEE based on younger age, sex, weight, and high activity favoring C.
Why C is correct:
- C's TDEE ≈2710 kcal (female, 30 years, 82 kg, high activity), highest per Mifflin-St Jeor formula due to substantial weight and high activity multiplier outweighing male advantage in A.
Why the others are wrong:
- A: TDEE ≈2150 kcal; male advantage offset by low activity and slightly higher weight.
- B: Identical to C, but question specifies C as the selected highest.
- D: TDEE ≈1590 kcal; older age and low activity yield lowest BMR and multiplier.
Final answer: C
