For a behavioral trait to evolve by natural selection, an individual's reproductive success must be affected by how the behavior is performed. This means that individuals who perform the behavior more effectively have a greater chance of survival and reproduction, passing on their genes and increasing the frequency of the behavior in the population. The other options (A, B, and D) are not necessarily required for a behavioral trait to evolve through natural selection.
