Assertion Vegetarians may take infertile eggs produced by purely female stocks in which male chickens are not kept.
Reason: Such eggs often called vegetarian eggs, are equivalent to milk in that both are animal products and do not produce life.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the Reason is not the correct explanation of the assertion
C. If assertion is true but the Reason are false
D. If both Assertion and Reason are false

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that vegetarians can consume infertile eggs produced by female-only flocks where no male chickens (roosters) are present. This means that these eggs are not fertilized and thus cannot develop into chicks.

2. **Clarifying Infertile Eggs**: Infertile eggs are the eggs that have not been fertilized by a rooster. Hens will lay eggs regardless of the presence of a rooster, but only fertilized eggs can develop into chicks.

3. **Vegetarian Perspective**: Since infertile eggs do not have the potential to develop into a living organism (a chick), they can be considered acceptable for vegetarians. This aligns with the vegetarian principle of not consuming products that involve the killing or potential life of animals.

4. **Understanding the Reason**: The reason provided states that these infertile eggs are often called vegetarian eggs and are equivalent to milk because both are animal products that do not produce life. This is accurate because both milk and infertile eggs are by-products of animals and do not lead to the birth of new animals.

5. **Conclusion**: Both the assertion and the reason are true. The assertion correctly states that vegetarians may consume infertile eggs, and the reason correctly explains why these eggs are considered acceptable for vegetarians.

6. **Final Answer**: The correct option is (a) - both assertion and reason are true, and the reason is the correct explanation of the assertion.
