While smoking contributes to vocal cord nodules, or singer's nodules, the most important cause of singer's nodules is vocal abuse, or singing.
These lesions are non-neoplastic growths that arise from reinke's space on the TRUE vocal cords.
Interestingly, pitch matters in this condition, with sopranos more likely to get this than baritones.
Only very rarely do these lesions show evidence of dysplasia, and therefore are not considered premalignant conditions.

Conclusion: I think "A" is the correct answer.

Correct Answer Answer

Hey Friends!
The answer is C, because glottic carcinoma has a good prognosis.

Regarding the choice A, I should say that this is the same sentence that I selected from Pathology BRS book, in which it was mentioned that "Singer's nodule is associated most commonly with heavy cigarette smoking".
