Explanation:

A blood test mainly measures blood - related components like glucose, lipids etc., not body fat percentage directly. A full - body MRI scan is expensive and not a common method for body fat percentage measurement. A bodyweight scale only measures total body weight, not body fat percentage. Dual energy x - ray (DXA) can accurately measure body fat percentage by differentiating between fat, lean tissue, and bone mass.

Answer:

D. Dual energy x - ray
