MULTIPLE CHOICE QUESTION

Given a scenario where a population of insects is exposed to a new pesticide and only a few survive, explain how this could lead to evolution in the population.
The survivors reproduce, passing on resistance genes, increasing the frequency of resistance in future generations.
The survivors mutate randomly, causing new species to form immediately.
The survivors stop reproducing, leading to extinction.
The survivors become less fit over time.
