**Core Concept**
Verrucous carcinoma of the larynx is a type of well-differentiated squamous cell carcinoma characterized by its slow growth, local invasiveness, and low metastatic potential. The management of this tumor requires a multidisciplinary approach, taking into account its location, size, and potential impact on laryngeal function.

**Why the Correct Answer is Right**
Endoscopic removal is the preferred treatment for verrucous carcinoma of the larynx due to its minimally invasive nature and ability to preserve laryngeal function. This approach allows for the removal of the tumor while minimizing the risk of complications and preserving the patient's voice quality and swallowing function. The use of endoscopic techniques, such as laser excision or cold steel excision, enables precise removal of the tumor while avoiding extensive surgical trauma.

**Why Each Wrong Option is Incorrect**
**Option A:** Pulmonary surgery is not relevant to the treatment of laryngeal tumors, as it involves procedures performed on the lungs rather than the larynx.
**Option B:** Electron beam therapy is a type of radiation therapy that is not typically used as the primary treatment for verrucous carcinoma of the larynx, as it may have limited effectiveness in controlling the tumor.
**Option C:** Total laryngectomy is a more aggressive surgical approach that involves removal of the entire larynx, which is not necessary for the treatment of verrucous carcinoma due to its localized nature and low metastatic potential.

**Clinical Pearl / High-Yield Fact**
Verrucous carcinoma of the larynx is often associated with exposure to tobacco smoke and alcohol, highlighting the importance of a thorough smoking and drinking history in the evaluation of patients with laryngeal tumors.

**✓ Correct Answer: D. Endoscopic removal**
