Reason:- Totally unrelated species could not complete for same resources.

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

Answer

To solve the assertion and reason question, we need to analyze both statements carefully.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states: "Competition always occurs between closely related species that compete for the same resources that are limiting."
- This implies that competition is exclusive to closely related species. However, this statement is incorrect because competition can occur between both closely related and unrelated species for limited resources.

2. **Understanding the Reason**:
- The reason states: "Totally unrelated species could not compete for the same resources."
- This statement is also incorrect. Unrelated species can and do compete for the same resources, such as water, food, or space, especially when those resources are limited.

3. **Evaluating the Truth of Each Statement**:
- Since both the assertion and the reason are false, we need to conclude that neither statement holds true.

4. **Conclusion**:
- Therefore, both the assertion and the reason are false.

### Final Answer:
Both the assertion and the reason are false.
