Answer:
Between
Explanation:
The correct preposition to fill in the blank is between: she had to decide between two things. This sentence indicates that there is a decision to be made, and the possibilities are two, which requires the preposition between. (She had to decide between two things, which is to have preference for one thing to another.)
