B. (A)-(iv), (B)-(iii), (C)-(i), (D)-(ii)
C. (A)-(iii), (B)-(ii), (C)-(iv), (D)-(i)
D. (A)-(i), (B)-(ii), (C)-(iii), (D)-(iv)

Answer

B

Explanation

(A) Tropospheric pollution: In the presence of pollutant, `SO_(2)` converts into `SO_(3)`.
`2SO_(2) + O_(2) to 2SO_(3)`
(B) In spring season, sunlight breaks HOCl and `Cl_(2)` to give chlorine radicals.
`HOCl overset(hv)to OH(g) + overset(.)(Cl)(g)`
These chlorine radicals deplete ozone layer
(C) High level of sulphur causes acid rain which reacts with marble and causes discolouring and disfiguring .
`CaCO_(3) + H_(2)SO_(4) to CaSO_(4)+ H_(2)O + CO_(2)`
(D) A chain reaction occurs from interaction of NO with sunlight in which NO is converted to `NO_2` which absorb energy from sunlight and breaks into NO and O , which causes photochemical smog.
`NO_(2)(g) overset(hv) to NO(g) + O(g)`.
