Which of the following behaviors is considered altruistic?

Food sharing is considered an altruistic behavior because it involves providing resources to other individuals, often at a personal cost or risk to the giver. Altruism, in this context, refers to actions that benefit others while potentially sacrificing one's own welfare or resources. In social species, food sharing can enhance the survival of group members, promote social bonds, and reinforce cooperative relationships.

The other behaviors, while they may occur in social animals, are typically not classified as altruistic. Infanticide, though it occurs in some species, usually serves to benefit the perpetrator by increasing their own reproductive success or resource availability. Dominance behavior often relates to establishing social hierarchies for access to resources and not necessarily includes selfless acts. High-ranking access to food is a product of social structure and competition, primarily benefiting those in power rather than providing benefit to others at a personal cost.
