A materials scientist studies the hypothetical gas-phase conversion \(\text{R(g)} \rightarrow \text{P(g)}\) in an exhaust-treatment prototype. The reaction-coordinate diagram for the uncatalyzed pathway is shown.

The scientist adds a solid catalyst that provides an alternative pathway with a lower activation energy. The chemical identities and states of the reactant and product remain unchanged. Which set of relative potential energies could represent the catalyzed pathway?
