To determine the correct option for the given statements, let's evaluate each statement individually and then assess their relationship:
Explanation: The sun is a massive energy source, radiating solar energy that reaches Earth in large quantities. Solar energy is indeed abundant, covering the whole planet, and can be harnessed through solar panels and other technologies. This statement is true.
Explanation: Solar energy is available throughout the year, although it may vary with weather conditions and geographical location. It is not limited to the summer season; hence, the availability of solar energy is not restricted to a particular season. This statement is false.
Conclusion: Based on the above evaluation, the correct answer is: A is true but R is false.
