Solution

The correct option is C The coefficients of the rate law are not, in any case, related to the reactants in the balanced reaction equation.
$r a t e = K [A]^{2} [B]^{2}$
The rate law is determined experimentally and the powers to which the concentration terms are raised in the rate law expression do not give any information about the coefficients of $A$ or $B$ in the balanced chemical equation.
