Explanation:
In Exp 1 and 4 ( Keeping the Conc. of [B] constant), when the concentration of A
 is quadrapled, the rate is also quadrapled. So Order with respect to A is 1

In Exp 2 and 3 ( Keeping the Conc. of [A] constant), when the concentration of B is doubled, the rate is quadrapled. So Order with respect to B is 2.

So r=k[A][B]2

Final Answer:

r = k[A][B]^2.  Correct option is D.
