Assertion : The sun is the ultimate source of all types of energies and sustains life on earth.
Reason : The solar energy gets converted into all types of energies present on the earth.

Options

A. If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.
B. If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.
C. If Assertion is CORRECT but Reason is INCORRECT.
D. If Assertion is INCORRECT but Reason is CORRECT.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that "The sun is the ultimate source of all types of energies and sustains life on earth."
- This is true because the sun provides energy that is essential for various processes on Earth, including photosynthesis in plants, which is the foundation of the food chain.

2. **Analyzing the Reason:**
- The reason given is "The solar energy gets converted into all types of energies present on the earth."
- This is also correct. Solar energy can be transformed into different forms of energy, such as chemical energy, electrical energy, and thermal energy.

3. **Explaining the Conversion of Solar Energy:**
- **Chemical Energy:** Through photosynthesis, plants convert solar energy into chemical energy stored in glucose.
- **Electrical Energy:** Solar cells (photovoltaic cells) convert solar energy directly into electrical energy.
- **Thermal Energy:** Solar energy can be harnessed to heat substances, which is a conversion to thermal energy.

4. **Interrelation of Energy Forms:**
- Once energy is converted into one form, it can be transformed into other forms. For example, electrical energy can be converted into mechanical energy or sound energy.

5. **Conclusion:**
- Since both the assertion and reason are correct and the reason explains the assertion, the correct answer is that both statements are true.

**Final Answer:**
- Both the assertion and reason are correct, and the reason supports the assertion.
