Select the most appropriate option to fill in blank No. 1.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. done to.
The blank is filled with "done to" because the phrase "the harm done to children" is a way to describe harm or damage that has been inflicted on someone.
The preposition "to" is used to indicate the recipient of the harm, and "done" indicates that the harm has been caused or carried out.
