Explanation:

Free nerve endings are the most common type of sensory nerve endings in the body. They are unencapsulated and can detect multiple types of stimuli. They respond to temperature (both heat and cold), pain (nociception), stretch (in some tissues), and touch (light touch). They are not limited to detecting just one of the other single - type stimuli like pain only, chemicals only, deep pressure only, or stretch only.

Answer:

temperature, pain, stretch and touch
