Answer

To solve the question regarding the female reproductive system and identify the correct statement, we can follow these steps:

### Step 1: Analyze the Options
We need to consider the statements provided about the female reproductive system and determine their validity.

### Step 2: Evaluate the First Statement
The first statement claims that the oviduct, uterus, and vagina constitute the female accessory duct.
- **Analysis**: This statement is correct. The oviduct (also known as the fallopian tube), uterus, and vagina are indeed part of the female reproductive tract and function as accessory ducts.

### Step 3: Evaluate the Second Statement
The second statement mentions that the narrow part of the oviduct is called the ampulla.
- **Analysis**: This statement is incorrect. The narrow part of the oviduct is actually referred to as the isthmus, while the ampulla is the wider section of the oviduct where fertilization typically occurs.

### Step 4: Evaluate the Third Statement
The third statement states that the uterus opens to the vagina through a narrow cervix.
- **Analysis**: This statement is correct. The cervix is indeed the narrow passage that connects the uterus to the vagina.

### Step 5: Evaluate the Fourth Statement
The fourth statement describes the mons pubis as a cushion of fatty tissue covered by skin and pubic hair.
- **Analysis**: This statement is also correct. The mons pubis is the rounded mass of fatty tissue situated over the pubic bone, covered with skin and pubic hair.

### Conclusion
From the analysis:
- The first statement is correct.
- The second statement is incorrect (the narrow part of the oviduct is not the ampulla).
- The third statement is correct.
- The fourth statement is correct.

Thus, the correct answer to the question "Which of the following statements regarding the female reproductive system is correct?" would be the first, third, and fourth statements, while the second statement is the incorrect one.

### Final Answer
The correct statements regarding the female reproductive system are:
1. Oviduct, uterus, and vagina constitute female accessory ducts.
2. The uterus opens to the vagina through a narrow cervix.
3. Mons pubis is a cushion of fatty tissue covered by skin and pubic hair.
