Among the options given, the incombustible substance is CCl4 (carbon tetrachloride).
Here’s why;
-> H2 (hydrogen gas) is highly combustible and burns with a pale blue, almost invisible flame.
-> C2H2 (acetylene) is also highly combustible and is often used as a fuel in welding torches.
-> S (sulfur) is combustible and burns with a blue flame, producing sulfur dioxide.
-> CCl4 (carbon tetrachloride), on the other hand, does not support combustion and is used as a fire extinguishing agent and in other applications where non-flammability is required.
