How do altruistic behaviors arise through natural selection?
A) By his/her actions, the altruist increases the likelihood that some of its genes will be passed on to the next generation.
B) The altruist is appreciated by other members of the population because their survivability has been enhanced by virtue of his/her risky behavior.

D) Altruistic behaviors lower stress in populations, which increases the survivability of all the members of the population.
