(C) The rate law for the reaction is given by $R = K[A]^n$,where $n$ is the order of reaction.Case $1$: When the concentration is increased $2$ times,the rate increases $4$ times.$4R = K[2A]^n$$4 = 2^n$$2^2 = 2^n \Rightarrow n = 2$Case $2$: When the concentration is increased $3$ times,the rate increases $9$ times.$9R = K[3A]^n$$9 = 3^n$$3^2 = 3^n \Rightarrow n = 2$Thus,the order of reaction is $2$.
