In the past, Plan (the charity that runs the Because I Am a Girl campaign) was a well respected charity. They match donors with “foster children” in developing countries and put monthly donations towards the child’s community. My mom always had foster children when I was growing up and she would hang their art work on the fridge alongside that of mine and my siblings.
However, these days, Plan spends an awful lot of money paying staff to harass people on the street. I strongly disagree with that marketing tactic and have reconsidering donating to Plan in the future.
The answer is C because the relative pronoun "that" is connecting "friend" to a clause. A relative pronoun connects nouns (friend) to phrases or clauses.
