**Core Concept**
The treatment of carcinoma of the appendix involves surgical intervention, often requiring a right hemicolectomy, especially if the tumor has invaded the appendix wall or if there's a high risk of lymph node metastasis. **Surgical oncology** principles guide the management, aiming to remove the tumor and prevent spread. The approach may vary based on the tumor's size, location, and histological type.

**Why the Correct Answer is Right**
The correct approach typically involves a **right hemicolectomy**, which is a surgical procedure to remove the right side of the colon, including the appendix and a portion of the intestine. This is particularly necessary for **carcinoid tumors** larger than 2 cm or for other types of appendix cancers that have a higher risk of spreading to lymph nodes. The goal is to achieve complete resection of the tumor and affected lymph nodes.

**Why Each Wrong Option is Incorrect**
**Option A:** This choice is incorrect because it may not specify the standard surgical approach for carcinoma of the appendix.
**Option B:** Similarly, this option is incorrect as it does not align with the recommended treatment for appendix carcinoma.
**Option D:** This choice is also incorrect as the treatment of carcinoma of the appendix usually involves more than just this option.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that the treatment approach can vary significantly depending on the size and type of the tumor, with smaller **carcinoid tumors** sometimes being managed with appendectomy alone. It's crucial to understand the specific characteristics of the tumor to guide the treatment plan.

**Correct Answer:** D. Right hemicolectomy.
