B. Endometrium `rarr` avascular and glandular layer of uterus
C. Mesometrium `rarr` muscular layer of uterus
D. Ampulla `rarr` site of fertilization

Answer

To solve the question "Which of the following is a correct match?" regarding parts of the female reproductive system, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Identify the first option: Mesosalpinx**
- The statement claims that mesosalpinx attaches the ovary to the abdominal cavity.
- **Analysis**: The mesosalpinx is actually a part of the broad ligament that supports the fallopian tubes, not the ovaries. Therefore, this statement is incorrect.

2. **Identify the second option: Endometrium**
- The statement claims that the endometrium is an avascular and glandular layer of the uterus.
- **Analysis**: The endometrium is indeed a glandular layer, but it is not avascular; it is highly vascularized, especially during the menstrual cycle. Thus, this statement is also incorrect.

3. **Identify the third option: Mesometrium**
- The statement claims that mesometrium is the muscular layer of the uterus.
- **Analysis**: The muscular layer of the uterus is called the myometrium, not mesometrium. The mesometrium refers to the part of the broad ligament that supports the uterus. Therefore, this statement is incorrect.

4. **Identify the fourth option: Ampulla**
- The statement claims that the ampulla is the site of fertilization.
- **Analysis**: The ampulla is indeed a part of the fallopian tube and is known to be the site where fertilization occurs. It is also involved in early embryo development. Thus, this statement is correct.

### Conclusion:
After analyzing all the options, the only correct match is:
- **Ampulla - Site of Fertilization (Correct Match)**

Therefore, the answer is **option D**.
