Yet, after the eggs hatch, the adults treat all of the larvae equally, sharing in the care of the entire population. Stem:Which one of the following, if true, most helps to explain burying beetles' apparently contradictory behavior? Correct Answer Choice:CChoice A:Burying beetles whose eggs hatch before their competitors' are more likely to have large broods than are burying beetles whose eggs hatch later. Choice B:The cooperation among adult burying beetles ensures that the greatest possible number of larvae survive. Choice C:Burying beetles are unable to discriminate between their own larvae and the larvae of other burying beetles. Choice D:Many of the natural enemies of burying beetles can be repelled only if burying beetles cooperate in defending the breeding site. Choice E:Most breeding sites for burying beetles can accommodate only a limited number of larvae.
