Solution

The correct option is D
(i) Combination reaction

(ii) Double Displacement reaction

(iii) Endothermic and combination reaction

Combination reaction:- When two or more substances combine to form a single substance it is called combination reaction.

Neutralisation reaction:- When an acid reacts with a base or an alkali it will form salt and water. It is a type of double displacement reaction in which ions exchange to form new compounds.

(i) Hydrogen $H_{2}$ and chlorine $C l_{2}$ combine to form hydrogen chloride $H C l$ gas. So it is a combination reaction.

(ii) Sodium hydroxide $N a O H$ reacts with hydrochloric acid $H C l$ to form sodium chloride $N a C l$ and water $H_{2} O$ . It is a neutralisation reaction which is a type of double displacement reaction.

(iii) Iron and sulphur (both elements) are heated together (endothermic) to form iron sulphide $F e S$ so it is also a combination reaction.
