For the reaction $A + B \to \text{Product}$,the rate of reaction becomes four times when the concentration of $A$ is doubled. If the rate of reaction does not change when the concentration of $B$ is doubled,the rate law for the reaction will be.....
- ARate $= k[A][B]$
- BRate $= k[A]^2$
- CRate $= k[A]^2[B]^1$
- DRate $= k[A]^2[B]^2$
