Based on the context, which of the following is the meaning of the word “beset” in the passage?

"To be overwhelmed and stressed." is correct because “beset” is used in the passage to describe how teachers feel when they can’t do their job properly. "To excel despite obstacles." and "To fight for what you need." reflect these difficulties, but each of them imply a fight, whereas “beset” is about being too restricted to excel. "To give up in the face of insurmountable odds." can’t be right because if teachers were giving up, they wouldn’t need donations.
