Sorry to say this (Admin from revise, Noida). But I think you have to read the 2nd paragraph's 2nd sentence. It mentions,"Every parent has the responsibility to instill in their children, the need to be charitable and kind.''
Ans 6:
Class : Class 7
"Every parent has the responsibility to instill in their children, the need to be charitable and kind."This shows that in the text, the sentence is mentioned. So the answer should be either A or D.
