Assertion: Evolution is called as organic evolution.
Reason: Evolution involves the living organisms.

Options

A. Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
B. Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion(A).

D. Assertion(A) is false but reason(R)is true.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that "Evolution is called organic evolution." This means that evolution is specifically related to living organisms.

2. **Understanding the Reason:**
- The reason provided is that "Evolution involves living organisms." This implies that the process of evolution is not just a random change but is specifically about changes that occur in living beings.

3. **Defining Evolution:**
- Evolution can be defined as the gradual and orderly changes that occur in living organisms over time. These changes can lead to the development of more complex forms from simpler ones.

4. **Connection Between Assertion and Reason:**
- The assertion is supported by the reason because evolution inherently involves living organisms. Since living organisms are made up of organic substances, the term "organic evolution" is appropriate.

5. **Conclusion:**
- Both the assertion and the reason are correct. The reason provides a valid explanation for why evolution is referred to as organic evolution, as it emphasizes the involvement of living organisms in the evolutionary process.

**Final Answer:**
Both the assertion and the reason are correct, and the reason correctly explains the assertion.
