which of the following is an effective way of measuring body fat percentage?
a) dual energy x - ray
b) bodyweight scale
c) blood test
d) full body mri scan

Explanation:

Dual - energy X - ray absorptiometry (DXA) is a highly accurate method for measuring body fat percentage. It uses two low - dose X - ray beams to differentiate between bone, fat, and lean tissue. A bodyweight scale only measures total body weight and cannot accurately determine body fat percentage. A blood test measures things like lipid levels (e.g., cholesterol, triglycerides) but not body fat percentage. A full - body MRI scan is very expensive and not typically used for routine body fat percentage measurement.

Answer:

A. Dual energy x - ray
