(B) The heat of combustion is directly proportional to the number of carbon and hydrogen atoms in the molecule.For the given gases:$CH_4$ (Methane): $1C, 4H$$C_2H_6$ (Ethane): $2C, 6H$$C_2H_4$ (Ethylene): $2C, 4H$$C_2H_2$ (Acetylene): $2C, 2H$Comparing the total number of atoms,Ethane $(C_2H_6)$ has the highest number of carbon and hydrogen atoms; therefore,it releases the maximum heat upon complete combustion.
