please select the best answer from the choices provided.
○ a
○ b
○ c
○ d

Explanation:

• Option A: Skin - fold measurements are not always reliable. Factors like the skill of the tester can affect results. Also, it provides more detail about body composition (like body - fat percentage) than stated.
• Option B: Skin - fold measurements require a trained professional. If the tester is not properly trained, they can mis - measure the skin folds (e.g., not pinching the correct amount of skin and subcutaneous fat), which makes it difficult to accurately determine body fat.
• Option C: Skin - fold measurements are typically taken from multiple sites (e.g., triceps, biceps, sub - scapular, suprailiac) not just the leg and forearm.
• Option D: Skin - fold measurements are not among the most expensive tests. More expensive and highly accurate tests include DEXA (Dual - Energy X - ray Absorptiometry).

Answer:

B. It can be difficult to determine one's body fat because the test administrator can easily make an error.
