Answer:
This is a case of natural selection
Explanation:
Mutations are a fundamental part of the process of evolution by natural selection. These are a random genetic modifications that occur on every organism - some are beneficial and others could be harmful or disadvantageous. Therefore, natural selection decides which mutations will stay on a population and which ones will be eliminated.
In this scenario, this mutation enables the male bird to carry out better mating rituals, therefore it would be considered beneficial as it helps the species to reproduce and survive. So, it will be passed on from generation to generation, making other individuals fit for survival.
This will be of good assistance

A) viral vectors is the best answer is viruses can be used to infect plants and change their DNA- bacteria aren't as good, as they can mostly be used to modify other bacteria only
