**Core Concept**
The management of cervical cancer stage IB involves a multidisciplinary approach, incorporating surgery, radiation therapy, and chemotherapy to achieve optimal outcomes. The primary goal is to eliminate the tumor while preserving surrounding tissues and organs.

**Why the Correct Answer is Right**
For stage IB cervical cancer, radical hysterectomy with pelvic lymphadenectomy is often the preferred treatment option. This surgical approach involves the removal of the uterus, cervix, upper portion of the vagina, and pelvic lymph nodes. The procedure aims to eliminate the tumor while preserving the patient's fertility and reducing the risk of recurrence.

**Why Each Wrong Option is Incorrect**
**Option A:** Radiation therapy alone may be used for more advanced stages or in cases where surgery is contraindicated, but it is not the primary treatment for stage IB cervical cancer.
**Option B:** Chemotherapy is often used in conjunction with radiation therapy for more advanced stages or in cases where the tumor has spread, but it is not typically used as the sole treatment for stage IB cervical cancer.
**Option C:** Neoadjuvant chemotherapy may be used in some cases to shrink the tumor before surgery, but it is not the standard treatment for stage IB cervical cancer.

**Clinical Pearl / High-Yield Fact**
Radical hysterectomy with pelvic lymphadenectomy is a critical procedure in the management of cervical cancer, and it is essential for surgeons to have a thorough understanding of the anatomy and surgical techniques involved to achieve optimal outcomes.

**Correct Answer:** C. Radical hysterectomy with pelvic lymphadenectomy.
