Final answer:
The sense related to perceiving softness and roughness is touch. This sense is mediated by specialized receptors in the skin, particularly mechanoreceptors, which are concentrated in sensitive areas like the palms, fingers, and face.
Step-by-step explanation:
The Sense Related to Softness and Roughness
The sense that is related to softness and roughness is touch. Touch, or tactile sense, is one of the five natural powers that humans have to receive information from the world. The ability to sense softness and roughness falls under this category because our skin has several types of receptor cells that detect different types of stimuli such as pressure and texture.
Under the touch category, mechanoreceptors in the skin respond to various tactile stimuli. These receptors provide feedback when we encounter different textures, determining if an object is soft, smooth, rough, or hard. The skin on our palms, fingers, and soles of the feet as well as our face, especially the lips and tongue, contains a high concentration of these receptors, making these areas particularly sensitive to touch sensations.
Therefore, the correct answer to which human sense is related to softness and roughness is: A) Touch.
