Answer:
The appropriate preposition to fill in the blank is "at".
The sentence should be: "The police officer is at the station."
Here's why:
1. The preposition "at" is commonly used to indicate a specific location or position. In this case, the police officer is at a particular location, which is the station.
2. "On" is not the correct preposition to use in this sentence because it implies being physically on top of something. However, in this context, the police officer is not physically on top of the station, but rather inside or at the location of the station.
Examples:
- The police officer is at the police station to gather information about the incident.
- I saw the police officer at the station earlier today while I was waiting for the train.
