Assertion :- During selection of good breeds beside high yielding potential, disease resistance is also consider.
Reason : - Diseases of live stock leads to under yield.

Options

A. If both Assertion & Reason are True & 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 is False.
D. If both Assertion & Reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that during the selection of good breeds, both high yielding potential and disease resistance are considered.
- This means that when breeders are choosing animals or plants for breeding, they look for those that can produce a lot (high yield) and those that can resist diseases.

2. **Evaluating the Reason:**
- The reason given is that diseases of livestock lead to under yield.
- This implies that if livestock are affected by diseases, their ability to produce (yield) is compromised, which is detrimental to the overall productivity of the breed.

3. **Analyzing the Relationship:**
- The assertion is true because both high yield and disease resistance are critical factors in selecting good breeds.
- The reason is also true as diseases can significantly reduce the yield of livestock, supporting the need for disease resistance in breeding.

4. **Conclusion:**
- Since both the assertion and the reason are true, and the reason correctly explains the assertion, we conclude that the assertion is correct, the reason is correct, and the reason provides a valid explanation for the assertion.

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