Which factor is a known risk factor for developing laryngeal cancer?

Explanation:
Tobacco exposure is a major risk factor for laryngeal cancer. Smoking delivers carcinogens to the laryngeal mucosa, causing DNA damage in squamous cells and promoting malignant transformation. The risk increases with how long and how much someone smokes and is further amplified by heavy alcohol use. The other options aren’t established risk factors for this cancer, so smoking stands out as the known contributor.
