(A) The calorific value depends on the composition of combustible gases present in the mixture. The order of calorific value is: Coal gas > Water gas > Producer gas. $1$. Coal gas: Contains high amounts of $H_2$ $(49\%)$,$CH_4$ $(32\%)$,and $CO$ $(8\%)$. $2$. Water gas: Contains $CO$ $(48\%)$ and $H_2$ $(50\%)$. $3$. Producer gas: Contains $CO$ $(35\%)$ and $N_2$ $(65\%)$. Since $CH_4$ has a very high calorific value,Coal gas possesses the highest calorific value among the given options. $CO_2$ is a non-combustible gas and has a calorific value of $0$.
