NEET UG 2010 — Biomolecules

The figure given below shows the conversion of a substrate into product by an enzyme. In which one of the four options (a-d), the components of reaction labelled as $A, B, C$ and $D$ are identified correctly? $\begin{array}{|c|c|c|c|c|} \hline & A & B & C & D \\ \hline \text{(a)} & \text{Potential energy} & \text{Transition state} & \text{Activation energy with enzyme} & \text{Activation energy without enzyme} \\ \hline \text{(b)} & \text{Transition energy} & \text{Potential energy} & \text{Activation energy without enzyme} & \text{Activation energy with enzyme} \\ \hline \text{(c)} & \text{Potential energy} & \text{Transition state} & \text{Activation energy with enzyme} & \text{Activation energy without enzyme} \\ \hline \text{(d)} & \text{Activation energy with enzyme} & \text{Transition state} & \text{Activation energy without enzyme} & \text{Potential energy} \\ \hline \end{array}$

Three of the following statements about enzymes are correct and one is wrong. Which one is wrong?
