Answer:
The piece of evidence that best supports the hypothesis that the evolution of altruistic behavior is driven by kin selection is "A meerkat protects the offspring of its sister from an attack by hawks." This is because kin selection is a theory in evolutionary biology that suggests that altruistic behaviors evolve because they increase the chances of survival of an individual's relatives, who share many of the same genes. In this case, the meerkat is protecting the offspring of its sister, who shares many of the same genes, thus increasing the chances of their survival and passing on those shared genes.
