Answer:
Option d
Explanation:
The question is to find the reason why our feet feel cooler on a tile floor than on a warm rug.
The reason is
i) the tile is a better heat conductor and it moves our body heat faster away from our skin.
ii) The rug is a good insulator and hence it slows down the flow of heat from our skin of touch and hence we feel warmer
So out of the four options
option d is right.
The rug is a better insulator than the tile.
