Solution

The correct option is D a-(ii), b-(iv), c-(iii), d-(i)

$A + B \to C + Heat$

Reactions in which energy is released in the form of heat along with the formation of products are known as exothermic reactions.

$2 A g C l (s) \to 2 A g (s) + C l_{2} (g)$

This is an example of a photolytic decomposition reaction as here decomposition of AgCl takes place in presence of light.

$A + B \to C - Heat$

Reactions which absorb energy in the form of heat along with the formation of products are known as endothermic reactions.

$2 H_{2} O (l) \to 2 H_{2} (s) + O_{2} (g)$

This reaction is known as electrolysis of water and is an electrolytic decomposition reaction.

Hence the correct option will be: a-(ii), b-(iv), c-(iii), d-(i)
