Hint: In winters we need to keep our bodies warm, and for that, we need to isolate our bodies from the cold and winter environment. To keep our body warm we need to wear such types of clothes that can protect our body’s heat from getting cold. That means, our body’s heat can protect us from cold weather.
Complete step by step solution:
Woollen clothes basically trap the air between them and as we know that air is a bad conductor of heat. So, the heat which is radiated from the body also gets trapped inside due to the air between the woollen clothes which doesn’t allow it to transfer the heat to the surroundings.
And also, we can also say that the woollen cloth is also a bad conductor of heat due to which it doesn’t allow the heat to transfer into the surroundings. Therefore, we use woollen clothes in the winter season because woollen is a bad conductor of heat.
Hence, option C is the correct answer.
Note:This question specifically asks about the winter but it is a general thing that woollen clothes keep us warm irrespective of the environment or season. Also note that as the woollen clothes do not allow heat to transfer into the surroundings, that is it resists the flow of heat from the surrounding to the body.
