B. Testes lie within the scrotum inside the abdominal cavity.
C. Multiple fission can be seen in Amoeba.
D. Both (A) and (C)

Explanation

To determine which of the statements is correct, let's analyze each statement step by step.

### Step 1: Analyze the first statement
The first statement discusses the process of menstruation. It states that if the ovum released from the ovary is not fertilized, it is shed along with blood during menstruation.

- **Explanation**: This is true. Menstruation is a monthly cycle in females that occurs after puberty. If the ovum is not fertilized, it is expelled from the body along with the uterine lining, which results in menstrual bleeding.

### Step 2: Analyze the second statement
The second statement mentions that the testes lie within the scrotum inside the abdominal cavity.

- **Explanation**: This statement is false. The testes are located in the scrotum, which is outside the abdominal cavity. This external position is crucial for maintaining a lower temperature necessary for sperm production.

### Step 3: Analyze the third statement
The third statement refers to multiple fission in amoeba, stating that amoeba reproduces asexually through this process.

- **Explanation**: This statement is true. Amoeba can reproduce asexually through a process called multiple fission, where the organism divides into several offspring.

### Step 4: Conclusion
Based on the analysis:
- The first statement is true.
- The second statement is false.
- The third statement is true.

Therefore, the correct statements are the first and third statements.

### Final Answer
The correct statements are 1 and 3.
