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 $A, B, C$A,B,C and $D$D are identified correctly? $$\begin{array}{|c|c|c|c|c|} \hline & A & B & C & D \\ \hline \text{(a)} & \text{Potential energy} & \text{Transition state} & \text{Activation energy with enzyme} & \text{Activation energy without enzyme} \\ \hline \text{(b)} & \text{Transition energy} & \text{Potential energy} & \text{Activation energy without enzyme} & \text{Activation energy with enzyme} \\ \hline \text{(c)} & \text{Potential energy} & \text{Transition state} & \text{Activation energy with enzyme} & \text{Activation energy without enzyme} \\ \hline \text{(d)} & \text{Activation energy with enzyme} & \text{Transition state} & \text{Activation energy without enzyme} & \text{Potential energy} \\ \hline \end{array}$$(a)(b)(c)(d)​APotential energyTransition energyPotential energyActivation energy with enzyme​BTransition statePotential energyTransition stateTransition state​CActivation energy with enzymeActivation energy without enzymeActivation energy with enzymeActivation energy without enzyme​DActivation energy without enzymeActivation energy with enzymeActivation energy without enzymePotential energy​​
