C
It measures the skin's thickness on one's leg and forearm.
D

Explanation
A skinfold test estimates body fat by measuring the thickness of folds of skin and underlying fat at several body sites. The result can be affected by how the administrator locates and pinches each fold, so mistakes can reduce its accuracy. Therefore, the best description is that it can be difficult to determine body fat because the administrator can make an error.
