Answer:
C.The percentage of essential body fat is the same for both males and females.
Explanation:
Among the given statements, only C is incorrect. Typically, on average, women have 5-12% more body fat than men. This has been mainly linked with the female hormones (e.g. oestrogen).

Secondly, they are suppose to carry a child at some stage of their life, so a better food supply and protection is necessary.
