**Question 14 of 25**

Consider the reaction profile shown below. Identify the transition state(s).

(Graph Description)
The graph is a reaction profile showing the change in enthalpy (H) with respect to the reaction coordinate. It features several labeled points along the curve:

- Point 1: Represents the starting reactants on a stable energy level.
- Point 2: A peak indicating a transition state with the highest energy point on the graph.
- Point 3: A slight dip showing an intermediate state with lower energy than points 2 and 4.
- Point 4: Another peak similar to point 2, indicating a second transition state.
- Point 5: The ending products on a stable, lower energy level than the starting reactants.

**Options:**
A) 1  
B) 2  
C) 3  
D) 2 and 4  
E) 5  

(The transition states are typically the highest points in the energy diagram, representing points 2 and 4.)
