  2. Air layer between two shirts works as a good conductor.

  3. The air layer between the two shirts behaves like an insulating media.

  4. No radiation of heat takes place.

C Correct answer
Explanation

Two thin shirts keep us warmer than one thick shirt because the air layer trapped between them acts as an insulator. Air is a poor conductor of heat, so this trapped layer reduces heat loss from the body more effectively than a single thick shirt would.
