## **Why the Correct Answer is Right**
The correct answer, ., indicates that early marriage and early childbearing are actually risk factors for cervical cancer. Early marriage often leads to early sexual activity, increasing the risk of HPV infection. Similarly, early childbearing may increase the risk due to the increased susceptibility to HPV infection and the potential for inadequate screening.

## **Why Each Wrong Option is Incorrect**

- **Option B:** is incorrect because it represents a protective factor or a non-risk factor in this context.
- **Option D:** is incorrect because it is a known risk factor. Smoking is associated with an increased risk of cervical cancer, likely due to the carcinogenic effects of tobacco on cervical cells.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **HPV vaccination** is a preventive measure against cervical cancer, targeting the most common high-risk HPV types. Screening programs, such as the Pap smear, are also crucial for early detection and prevention of cervical cancer.
