Mud houses are cooler in summers and warmer in winters as compared to brick houses because A. Mud is a good conductor B. Mud is a bad conductor C. Mud is a poor insulator D. Evaporation of water causes cooling in summers and sunlight coming through holes causes warming in winters

The correct answer is: B. Mud is a bad conductor.

Mud is a poor conductor of heat, which means that it does not transfer heat very well. This makes mud houses cooler in the summer and warmer in the winter than brick houses. In the summer, the

sun’s heat is not transferred very well through the mud walls, so the inside of the house stays cooler. In the winter, the heat from the inside of the house is not transferred very well through the mud walls, so the inside of the house stays warmer.

Option A is incorrect because mud is a bad conductor, not a good conductor. Option C is incorrect because mud is a good insulator, not a poor insulator. Option D is incorrect because evaporation of water does not cause cooling in summers and sunlight coming through holes does not cause warming in winters.
