B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

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

### Step 1: Understand the Assertion
The assertion states that "the animals which give birth to young ones are called oviparous."
- **Explanation**: This statement is incorrect. Animals that give birth to live young are called **viviparous**. Oviparous animals are those that lay eggs.

### Step 2: Understand the Reason
The reason states that "earthworms lay eggs and are unisexual."
- **Explanation**: This statement is also incorrect. While it is true that earthworms lay eggs, they are not unisexual. Earthworms are **hermaphrodites**, meaning that each individual has both male and female reproductive organs.

### Step 3: Conclusion
Since both the assertion and the reason are incorrect, we conclude that the answer to the assertion-reason question is that both statements are false.

### Final Answer
Both the assertion and the reason are incorrect.
