Solution

The correct option is B $C H C l_{3} + O_{2} a l c o h o l ⟶ 2 C O C l_{2} + 2 H C l$
Catalyst alters the rate of reaction by altering activation energy of reaction.
It could be positive catalyst which increases rate and can be negative catalyst which decreases rate of reaction.
According to the given options A, C, D have positive catalysts but in option B alcohol ( $C_{2} H_{5} O H$ ) is a negative catalyst for oxidation of $C H C l_{3}$ which prevents reaction of chloroform with oxygen to give $C O C l_{2}$ .
