Solution

The correct option is D bleaching powder
Bleaching powder with chemical name calcium oxychloride ( ${CaOCl}_{2}$ ) has yellowish-white colour. It releases chlorine gas on reaction with dilute hydrochloric acid ( $HCl$ ) and sulphuric acid ( $H_{2} {SO}_{4}$ ). The reactions are given below:

${CaOCl}_{2} (s) + H_{2} {SO}_{4} (aq) \to {CaSO}_{4} (s) + {Cl}_{2} (g) + H_{2} O (l)$
${CaOCl}_{2} (s) + 2 HCl (aq) \to {CaCl}_{2} (s) + {Cl}_{2} (g) + H_{2} O (l)$
