**Core Concept**
Hoarseness of voice, also known as dysphonia, is a symptom characterized by a change in the quality or pitch of the voice. This symptom can be caused by various factors, including laryngeal pathology, neurological disorders, or systemic diseases.

**Why the Correct Answer is Right**
In the context of the question, hoarseness of voice is often associated with the progression of a particular disease. The correct answer is related to the involvement of the recurrent laryngeal nerve, which supplies motor innervation to the posterior cricoarytenoid muscle, responsible for opening the glottis. As the disease process advances, the recurrent laryngeal nerve can be compressed or damaged, leading to vocal cord paralysis and hoarseness of voice.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because hoarseness of voice is not typically an early symptom of this condition.
**Option B:** This option is incorrect because, while this condition can cause hoarseness of voice, it is not the most characteristic or earliest symptom.
**Option C:** This option is incorrect because hoarseness of voice is not typically an early symptom of this condition.

**Clinical Pearl / High-Yield Fact**
The recurrent laryngeal nerve is the longest nerve in the larynx, with a long course that makes it susceptible to compression or damage from various causes, including thyroid surgery, lung cancer, or aortic aneurysms.

**Correct Answer:** C. Lung Cancer.
