The correct option is C Closely matching curve 3
Darwin's Theory of Evolution by Natural Selection states that more individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive and others will die.
Curve 3 represents a survivorship curve in which many individuals die early in life. It is common among species with large broods and low parental investment.
