**Core Concept**
The staging of cervical cancer is based on the extent of the tumor's spread, which is crucial for determining prognosis and treatment. The **International Federation of Gynecology and Obstetrics (FIGO)** staging system is commonly used.
**Why the Correct Answer is Right**
When carcinoma of the cervix extends up to the lateral pelvic wall, it indicates a more advanced stage of the disease. This spread signifies that the tumor has extended beyond the cervix and is now involving the pelvic sidewall, which is a key landmark in cervical cancer staging.
**Why Each Wrong Option is Incorrect**

**Option B:** This stage involves the tumor extending beyond the cervix but not to the pelvic sidewall.
**Option D:** This represents an even more advanced stage with the tumor extending beyond the pelvic sidewall.
**Clinical Pearl / High-Yield Fact**
A key point to remember in cervical cancer staging is the significance of the tumor's extension to the pelvic sidewall, which marks a transition to a more advanced stage.
**Correct Answer: B. III**
