Match the occupational diseases in Column I with the causative agent from Column II.

Column I	Column II
1. Blood dyscrasias	A. Cotton fibre dust
2. Bagassosis	B. Sugarcane dust
3. Byssinosis	C. Coal dust
4. Anthracosis	D. Ionizing radiation

Options:

Correct option is D

Blood dyscrasias → D (Ionizing radiation): Long-term exposure to ionizing radiation (e.g., in radiology, nuclear industries) can cause blood-related disorders such as leukemia and anemia.
Bagassosis → B (Sugarcane dust): An occupational lung disease caused by inhalation of sugarcane bagasse dust, leading to hypersensitivity pneumonitis.
Byssinosis → A (Cotton fibre dust): Also called “brown lung disease,” it is caused by prolonged inhalation of cotton dust, common in textile industry workers.
Anthracosis → C (Coal dust): Known as “black lung disease,” caused by inhalation of coal dust among coal miners, leading to lung damage and fibrosis.
Correct match: 1-D, 2-B, 3-A, 4-C → Option (d).
