Passage - VIII :
In this passage five observation are given. Question are asked with reference to the given observations
Observation (i) Gaseous oxygen is colourless whereas liquid and solid oxygen are coloured substance.
Observation (ii) When `O_(2)` is cooled below a certain temperature its paramagnetic character decreases.
Observation (iii) In ice `H_(2)O` molecules are H bonded
Observation (iv) Ozone is responsible for tailing of `Hg(l)`
Observation (v) `O_(3)(g)` is almost unavailable in lower atmosphere
Reference to observation (v) `O_(3)(g)` is unavailable in lower atmosphere because -

Options

A. at lower altitude `O_(3)` produced is decomposed to `O_(2)` due to the higher temperature
B. at lower temperature there is noise pollution, therefore `O_(3)` produced is decomposed to `O_(2)`
C. `O_(3)(g)` is heavier than air, hence available in the coal mines
D. in the lower altitude UV radiation of higher frequencies required for the dissociation of gaseous `O_(2)` to atomic oxygen, are unavailable

Answer

D

Explanation

In the lower altitude UV radiation of higher frequencies required for the dissociation of gaseous `O_(2)` to atomic oxygen, are unavailable
