Which piece of evidence would best support the argument for kin selection as a mechanism for the evolution of altruistic behavior?

A. a penguin protects its chick from seagulls
B. a clown fish helps clean parasites off of a sea anemone
C. an antelope gets separated from the herd and killed by predators
D. a hipp0 stops a crocodile from eating an antelope

A. a penguin protects its chick from seagulls

This evidence would best support the argument for kin selection as the penguin is exhibiting altruistic behavior towards its offspring, who share genetic material with the parent. This behavior enhances the likelihood of the offspring surviving and passing on their shared genes, thereby supporting the idea of kin selection.
