The correct option is (a) true

To elaborate: Calcium carbonate is heated and results in the formation of calcium oxide and carbon dioxide and then calcium oxide combines with carbon in order to form calcium carbide and carbon monoxide, when calcium carbide combines with water it forms calcium hydroxide as well as an alkyne that is Ethyne C2H2.
