In which situation will natural selection be seen most clearly?
Answer and explanation
Correct answer: Insects with favourable colour survive more and leave more offspring
Natural selection requires three linked conditions: variation among individuals, a difference in survival or reproduction, and inheritance of the advantageous feature. If better-coloured insects escape predators more often and leave more offspring, their colour may become more frequent in later generations. Thus option A shows selection clearly. B removes variation, C removes reproduction, and D provides no selective difference.
