Answer:

2. B.

Explanation:

The letter B represents the activated complex.

The activated complex is the intermediate that is formed between the states of reactants "F" and products "G".

Letter A represents the activation energy of the reaction, that is the difference in potential energy between the reactants "F" and activated complex "B".

Letter C represents the enthalpy change of the reaction, that is the difference in potential energy between products "G" and reactants "F".

Letter D represents the potential energy of products "G".

Letter E represents the potential energy of reactants "E".
