Final answer:
The movie was over two hours long, implying a duration longer than two hours but not exactly specified; hence, the probable answer is 3 hours.
Step-by-step explanation:
The duration of the movie mentioned in the question was over two hours. Therefore, we can infer that the movie was longer than two hours but does not clearly specify how much longer. This information implies that the only correct answer from the provided options that is more than two hours would be 3 hours, which makes it the most probable answer.
