A	2
B	5
C	4
D	10

Explanation:

Detailed explanation-1: -Acetylene, C2H2, is used in welding torches. The combustion of acetylene is described by the balanced chemical equation. 2C2H2 gas plus 5O2 gas react to form 4CO2 gas plus 2H2O gas.

Detailed explanation-2: -Acetylene is used in welding and cutting processes. The welding process using acetylene is known as cutting oxy-fuel or cutting coal. This method is used for cutting or welding materials which require temperatures of up to 3, 500 ° C (6, 330 ° F). Acetylene is capable of producing the hottest flame of all other gases.
