Solution

The correct options are
A $O_{2} (g) + U V ⟶ O (g) + O (g)$
B $O_{2} (g) + O (g) ⟶ O_{3} (g)$
C $\cdot C l (g) + O_{3} (g) ⟶ C l \cdot O (g) + O_{2} (g)$
The first three reacions occur in ozone layer of the atmosphere. Ozone layer is present in the stratosphere.
So, the first three reactions occur in stratosphere.
The reaction of $S O_{3} a n d H_{2} O$ to give $H_{2} S O_{4}$ occur in troposphere. This causes acid rain.
