Solution

The correct option is C $C, H, S$
The elements present in the compound are $C, H, S$ . Carbon on burning gives $C O_{2}$ , which turns lime water milky. The second compound is $H_{2} O$ , which turns cobalt chloride paper pink. Third compound is $S O_{2}$ . It is acidic in nature and hence, formed an aqueous solution of pH $3$ nearly. Hence, option C is correct.
