Show answer and explanation
Correct answer: (c) A-2, B-3, C-1, D-4
Explanation
Blue Vitriol (CuSO₄·5H₂O) acts as a fungicide; Eosin is a red dye used as red ink.
Silver iodide (AgI) is used for cloud seeding to cause artificial rain; Zinc phosphide (Zn₃P₂) is a rodenticide.
This gives A-2, B-3, C-1, D-4.
