Solution

The correct option is B Temperature is decreased
$2 S O_{2} (g) + O_{2} (g) \to 2 S O_{3} (g)$
The above reaction is exothermic. The yield of $S O_{3}$ will be maximum at lower temperatures, higher pressures and an increase in the concentration of $S O_{2}$ and $O_{2}$ .
(According to Le Chatelier's principle)
