Assertion :- Any population has built in variation in characteristics.
Reason :- Variations are always stable and inheritable.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is a not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that "Any population has built-in variation in characteristics." This is a true statement and aligns with Charles Darwin's theory of natural selection, which emphasizes that variations exist within a population.

2. **Understanding the Reason:**
- The reason provided is "Variations are always stable and inheritable." While it is true that variations can be inheritable, they are not always stable. Variations can change over time due to environmental factors, mutations, and other influences.

3. **Evaluating the Truth of the Statements:**
- The assertion is true because populations do exhibit variations in characteristics.
- The reason is false because variations are not always stable; they can fluctuate and change.

4. **Conclusion:**
- Since the assertion is true and the reason is false, we conclude that the correct relationship is that the assertion is true, but the reason does not correctly explain the assertion.

**Final Answer:**
- The assertion is true, but the reason is false.
