The correct answer is "Sensation." Sensation is the skin function that relates to the detection of touch, temperature, and pain. The skin contains nerve endings that allow us to sense these external stimuli, providing important feedback about our environment and potential dangers. Protection, secretion, and absorption are also important skin functions, but they do not specifically relate to the detection of touch, temperature, and pain like sensation does.
