Free nerve endings are the sensory receptors responsible for detecting pain, heat, and cold. It is the most suitable tactile receptor in this scenario because Ye-eun got burned, causing damage to her skin, which would activate these receptors. Merkel's discs are responsible for light touch, Ruffini's end-organs detect skin stretch, and Meissner's corpuscles perceive pressure and low-frequency vibrations, making them less likely to be activated in this scenario.
