Study the graph.

The graph shows energy over the course of a chemical reaction. At the start of the reaction, the reactants have a medium amount of energy. Then the level of energy peaks, and starts to quickly decline. The product of the reaction has a low amount of energy.

Based on the information in the graph, choose the statement that best describes the reaction it depicts.

A. The reaction absorbs energy.
B. The reaction releases energy.
C. The reaction fails to proceed because of insufficient energy.
D. The reaction fails to proceed because it does not involve an energy change
