The correct answer , as the comment above said, is B. I want to add something:
Some people think that morality is a question of how we treat others, so when a person does something for himself or herself, it doesn't count as an act of morality.
Most Christian writers of the Middle Ages were unbashed about the individual reward of the afterlife. But many years later, Christianity brought a major innovation emphasizing that a person should do what it is needed to save his/her own soul. Jesus was clear when he said he came to save individuals.
