Correct Answer is C

A. Cutaneous transpiration: While cutaneous transpiration (evaporation of sweat from the skin) contributes to water loss, it is not the primary mechanism controlling water output.
B. Drinking: Drinking affects water intake rather than output. It does not directly control how much water is excreted from the body.
C. Urine volume: Urine volume is the primary means by which the body regulates water output. The kidneys adjust urine volume to maintain fluid balance and homeostasis.
D. Sweating: Sweating contributes to water loss but is not the primary mechanism for controlling overall water output compared to urine production.
