## Core Concept
Rhabdomyosarcoma is a type of soft tissue sarcoma that originates from skeletal muscle cells. It is the most common soft tissue sarcoma in children and adolescents. Treatment of rhabdomyosarcoma involves a multidisciplinary approach.

## Why the Correct Answer is Right
The correct approach for treating rhabdomyosarcoma includes **surgery**, **chemotherapy**, and **radiotherapy**. Surgery is used to remove the tumor when possible, chemotherapy is used to treat microscopic disease and to shrink the tumor before surgery, and radiotherapy is used to control local disease. This multimodal treatment approach aims to achieve the best possible outcome in terms of local control and survival.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because a single modality of treatment (like surgery alone) is generally not sufficient for managing rhabdomyosarcoma effectively.
- **Option B:** This option might seem plausible but is incorrect because it likely represents an incomplete treatment approach for rhabdomyosarcoma.
- **Option C:** Similarly, this option is incorrect for potentially lacking one of the critical components of rhabdomyosarcoma treatment.

## Clinical Pearl / High-Yield Fact
A key point to remember is that the treatment of rhabdomyosarcoma is often stratified based on the **Intergroup Rhabdomyosarcoma Study (IRS) grouping system**, which guides the intensity of therapy. Additionally, **chemotherapy** plays a crucial role in the management of this disease, even in cases where surgery and/or radiation are used.

## Correct Answer Line
**Correct Answer: D.**
