p. Peroxy acetyl nitrate | 1. Waste incineration |
q. Polycyclic aromatic hydrocarbons | 2. Global warming |
r. Dioxins | 3. Photochemical smog |
s. Indigo | 4. Carcinogens |
t. IR active molecules | 5. Vat dye |
Solution:
p) Peroxy acetyl Nitrate: (3) It is a secondary pollutant present in photochemical smog
q) Polycyclic aromatic hydrocarbons: (4) Excessive exposure to polycyclic aromatic hydrocarbons (PAHs) often results in lung cancer
r) Dioxins: (1) When you incinerate waste, some dioxin formation is inevitable.
s) Indigo: (5) Vat dyes are a class of dyes that are classified as such because of the method by which they are applied. Vat dyeing is a process that refers to dyeing that takes place in a bucket or vat. The original vat dye is indigo.
t) IR active molecules: (2) Cause Global warming
Hence option A is correct
