I understand why C is correct. But my question is about titrations...I don't remember where, but I think there was another question in one of my practices where you dissolve an acid in a strong BASE and then titrate it with a strong base. Why would we dissolve phenylalanine in a strong ACID and then titrate it with a strong base in this question? I might be remembering this wrong, but I want to make sure.
