Fill in the blank with the most appropriate option.
I fear she is fretting about something, I wish I could __________ what it is
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. find out.
The correct choice is "find out" because it means to discover or learn something, fitting the context of wanting to know why she is fretting.
The other options are less suitable: "query" refers to asking a question, "investigate" is too formal for this context, and "fall out" means to have a disagreement, which doesn't apply here.
