(B) The rate law for the reaction is given by: $r = k[A]^1[B]^2$. If the concentration of $B$ is increased $3$ times,the new concentration becomes $[B'] = 3[B]$. The new rate is $r_{new} = k[A][3B]^2$. $r_{new} = k[A] \times 9[B]^2 = 9 \times (k[A][B]^2)$. $r_{new} = 9r$. Therefore,the reaction rate increases $9$ times.
