For a reactions `A + B rarr` product, it was found that rate of reaction increases four times if concentration of `'A'` is doubled, but the rate of reaction remains unaffected. If concentration of `'B'` is doubled. Hence, the rate law for the reaction is

A

rate `=K [A] [B]`

B

rate `=K [A] ^(2)`

C

rate `=K[A]^(2)[B]`

D

rate `=K [A]^(2)[B]^(2)`
