The atmosphere of asbestos mines contains asbestos dust. Which of the following diseases can be caused by long-term exposure to this?

Correct option is A

Sol. Asbestosis is a chronic lung disease caused by prolonged inhalation of asbestos fibers. It leads to scarring of lung tissue and breathing difficulty, and is common among workers in asbestos-related industries.
Explanation of each option: • (a) Asbestosis – Correct. Long-term exposure to asbestos dust leads to this condition, which may progress to lung cancer or mesothelioma. • (b) Asbestosis silica – Incorrect combination; no such disease classification exists. • (c) Silicosis – Caused by inhalation of silica dust, not asbestos. It is seen in stone-cutting or sandblasting industries. • (d) Silica asbestosis – Again, not a valid medical term. It confuses two distinct occupational diseases.
