Solution

The correct option is A $C a C_{2}$
Calcium carbide $(C a C_{2})$ when reacts with oxygen forms calcium oxide and carbon dioxide gas evolve in the reaction.
$C a C_{2} + \frac{5}{2} O_{2} \to C a O + 2 C O_{2}$

Nitrogen gas present in air can react with $C a C_{2}$ and produce calcium cyanamide ( $C a C N_{2}$ ).
$C a C_{2} + N_{2} \to C a C N_{2} + C$

$C a C_{2}$ can consume oxygen and nitrogen gases from air at $1000^{o} C$ .
Hence, option(A) is correct.
