Answer:

The gas formed which extinguishes a burning candle is carbon dioxide.one of the compound formed is calcium chloride hence the compound A is calcium carbonate (CaCO3) as when metal carbonate or metal hydrogencarbonate react with acid to produce a metal salt along with carbon dioxide and water.

CaCO3 + 2HCL ------>CaCl + CO2 + H2O

As metal compound released is Calcium Chloride the gas evolved here is CO2. Hence metal A should be Calcium Carbonate. Hence the reaction between Calcium Carbonate and HCl is

\small\mathrm\red{CaCO3 (s) + 2HCl (Aq) → CaCl2( Aq) + CO2 (g) + H2O (l)}
