2. Paul and Simon couldn’t agree ................. which film to see * 1 бал A - with B - to C - in D - on

The correct preposition is **on**.

* **with** is used to show agreement or support.
* **to** is used to show movement or direction.
* **in** is used to show location or time.
* **on** is used to show preference or opinion.

In this sentence, Paul and Simon are trying to decide **which film they prefer**, so **on** is the most logical choice.
