D. A and B

Answer

To solve the question, we need to evaluate each statement regarding animals with specific characteristics (outside ears and hair on their body) and determine whether they give birth to young ones or lay eggs.

### Step-by-Step Solution:

1. **Evaluate Statement A**:
- "Animals that have outside ears and hair on their body give birth to the young ones."
- This statement is **true** because animals with these characteristics are typically mammals, and mammals give live birth.

2. **Evaluate Statement B**:
- "Animals that do not have outside ears and hair on their body lay eggs."
- This statement is also **true**. Animals without outside ears and hair are often reptiles or birds, which are oviparous (they lay eggs).

3. **Evaluate Statement C**:
- "Animals that do not have outside ears and hair on their body give birth to the young ones."
- This statement is **false**. Animals without these features typically lay eggs rather than giving live birth.

4. **Evaluate Statement D**:
- "Animals that have outside ears and hair on their body lay eggs."
- This statement is **false**. As previously established, animals with outside ears and hair (mammals) give birth to live young, not eggs.

### Conclusion:
The correct statements are A and B. Therefore, the answer is that the correct options are A and B.
