Dear teachers,
I came across the following question today, and I am puzzled, so please help me.
____________ by the man, she hid herself in a cave.
A. Being followed B. Followed
C. Having followed D. Having been followed

They are all just about possible, but none is very natural - C means something different, of course.

I would say: As (= since/because) she was being followed by a/the man, she hid in a cave.
