Motives are classified according to the place from which they arise. Those that spring from bodily needs and inborn tendencies are called natural or innate; those that grow out of living together in a group are named after that group life itself.

Ideals held up by a community, the position a person occupies among others, and the web of ties with family, friends and neighbours all belong to collective living. A motive born out of these forces is therefore given the name of the sphere that produced it, and it varies from one community to another exactly because that sphere varies.

Hunger, thirst and the urge for safety would be inborn, so the first and the fourth labels do not fit. The label that merely says the motive was gained later covers a much wider class, which also includes likings and habits formed by repetition without any other person being involved. The stem names ideals, status and relationships, so the narrower and more exact label is required.

Social motive option is correct.
