Answer

To solve the question "Find the correct options," we will analyze each statement provided and determine whether they are true or false.

### Step-by-Step Solution:

1. **Statement A: Testosterone influences male secondary sexual characters.**
- **Analysis:** Testosterone is indeed an androgen (male hormone) that plays a crucial role in the development of male secondary sexual characteristics such as facial hair, deep voice, and muscle growth. Therefore, this statement is **correct**.

2. **Statement B: Gestation period in rabbit is about 276 days.**
- **Analysis:** The gestation period for rabbits is approximately 27 to 30 days, not 276 days. The 276 days gestation period is more aligned with humans. Thus, this statement is **incorrect**.

3. **Statement C: Bulbo-urethral gland secretes a vaginal lubricant.**
- **Analysis:** The bulbo-urethral glands (also known as Cowper's glands) are male accessory glands that produce a pre-ejaculatory fluid that helps lubricate the penis, not the vagina. Therefore, this statement is **incorrect**.

4. **Statement D: Placenta secretes estrogen.**
- **Analysis:** The placenta does secrete several hormones, including estrogen and progesterone, which are crucial for maintaining pregnancy. Therefore, this statement is **correct**.

### Conclusion:
The correct options are **A (Testosterone influences male secondary sexual characters)** and **D (Placenta secretes estrogen)**.

### Final Answer:
- Correct options: A and D.
