In which sentence is the action arrow pointing in the correct direction?

A---------> The children were told to be quiet by the teacher.
B<––––– The children were told to be quiet by the teacher.

Verified Answer :

The correct answer is b. <––––– The children were told to be quiet by the teacher.

That is because this is a passive construction and means that the subject that is actually the teacher influences the children, not the other way around.
