D.5 3 1 2 4
Explanation
The correct match is A → 3, B → 4, C →1, D → 5, E → 2. Peroxyacetyl nitrate is the main component formed in photochemical smog. Polycyclic aromatic hydrocarbons act as carcinogens. Dioxins are used to burn the waste into ashes. Indigo is called as vat dye because the dyeing with indigotin was carried out in wooden vats in the form of water soluble indigotin-white. IR active molecules are responsible for global warming.
