The correct answer is: to.
The preposition “to” is used to indicate the end of a period of time or the destination of an action. In this case, the speaker is indicating that they listened to what the woman said until the end.
The other options are not correct because they do not make sense in the context of the sentence. The preposition “for” is used to indicate a period of time during which something happens. The preposition “from” is used to indicate the starting point of a journey or action. The preposition “at” is used to indicate a specific point in time or place.
Here are some examples of how the other prepositions could be used in a sentence:
- I waited for her to finish talking.
- She came from the kitchen.
- I looked at her in surprise.
