The correct answer is B. Winter.
In winter, the weather is cold and we need more energy to stay warm. Fat is a good source of energy, so we need more of it in winter.
Spring is a time of new growth, and we need more energy to support this growth. However, the weather is still relatively warm, so we don’t need as much fat as in winter.
Summer is the hottest season, and we need to stay cool. Fat can make us feel hot, so we don’t need as much of it in summer.
The rainy season is a time of high humidity, and we need to stay hydrated. Fat can make us feel bloated, so we don’t need as much of it in the rainy season.
