If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

(A) The rate expression $\frac{dX}{dt} = k[A]^m[B]^n$ indicates that the reaction rate depends only on the concentrations of reactants $A$ and $B$.The order of the reaction with respect to $C$ is $0$,which means the rate of the reaction is independent of the concentration of $C$.Since the rate law is experimentally determined and explicitly excludes $C$,the Reason correctly explains why $C$ does not appear in the rate expression.
