What is the recommended range of essential body fat necessary for normal physiological function?
The correct answer is B. 3-5% for males; 8-12% for females. Essential body fat is the minimum amount of fat required for normal physiological function, including hormone production and organ protection. The thresholds differ by sex due to sex-specific fat stores.

Why each option
Essential body fat is the minimum amount of fat required for normal physiological function, including hormone production and organ protection. The thresholds differ by sex due to sex-specific fat stores.
The male range of 3-5% is correct, but a female minimum of 6-8% is too low and does not account for sex-specific essential fat stores.
The accepted essential body fat range is 3-5% for males and 8-12% for females. Females require a higher minimum due to sex-specific fat deposits including those supporting reproductive hormonal function; falling below these thresholds can impair normal physiological processes such as hormone regulation and organ cushioning.
These percentages (6-13% male; 13-22% female) describe athletic body fat ranges, not the minimum essential fat thresholds.
These values (13-18% male; 20-35% female) describe average or acceptable body fat ranges for the general population, not essential minimums.
