Explanation:
The correct answer is option 'A', which is Spring.

Reason:
Spring is the season that falls between winter and summer. During this time, the weather is neither hot nor cold. Let's explore why this is the case.

1. Transition from Winter to Summer:
- Spring is a transitional season between winter and summer. It marks the end of the cold winter season and the beginning of warmer weather.
- As winter comes to an end, the temperature gradually starts to rise, but it is not yet hot enough to be considered summer weather.
- Similarly, during the transition from summer to winter, fall or autumn is the season when the temperature is neither hot nor cold.

2. Typical Spring Weather:
- In spring, the average temperature is generally mild and moderate, with a gradual increase from the colder winter temperatures.
- The days become longer, and the amount of sunlight increases, contributing to the warming trend.
- However, spring can still have occasional fluctuations in temperature, with cooler days and warmer days, but overall, it is a season of moderate temperatures.

3. Growth and Renewal:
- Spring is often associated with new growth and renewal in nature. It is the time when plants start to bloom, trees regain their greenery, and animals come out of hibernation.
- The mild temperatures of spring provide favorable conditions for plants and animals to thrive and reproduce.
- The transition from cold to warm weather creates an ideal environment for the rejuvenation of the natural world.

Conclusion:
In summary, spring is the season when the weather is neither hot nor cold. It serves as a transition between the cold winter and the hot summer, with moderate temperatures that support the growth and renewal of nature.
