A $\left(1\right)$
B $\left(2\right)$
C $\left(3\right)$
D $\left(4\right)$

Correct answer

C. $\left(3\right)$

Step-by-step solution

The curve contain three activated complex as shown below in the curve.In the curve P and Q are the intermediates. The step with the highest activation energy is the rate determining step. Hence, in the given reaction, two intermediates, three activated complexes are involved and step-II is the rate determining step.
