Which statement about the described sense is true?

• A. It requires direct contact with the body via contact receptors
• B. It does not require any contact
• C. It uses only chemical signals
• D. It relies on magnetic fields

Answer: (A)

Touch relies on mechanoreceptors in the skin that are activated when something physically contacts the body. These receptors convert mechanical energy from direct contact into neural signals that travel to the brain. Because this sense depends on direct interaction with the skin, it requires contact to be detected. Senses like vision and hearing work without direct contact—the stimulus (light or sound waves) reaches the sensory organs from a distance—so the idea of no contact doesn’t apply to touch. Chemical signals drive taste and smell, not tactile touch, and magnetic fields aren’t a mechanism for human touch. So the statement that this sense requires direct contact with the body via contact receptors is the best fit.
