Answer 1

Evolution by natural selection

Answer 2

Answer:

The correct answer will be-natural selection which will lead to evolution.

Explanation:

Antibiotic resistance is the property of the prokaryotes like bacteria which helps in the survival of the species. The bacteria become resistant to the antibiotic by changing the sequence of the DNA present in them mainly on the plasmid.

In the given question since bacteria acquired resistance to the antibiotic which favoured the survival of the species, therefore, this will be considered the case of the natural selection in which nature selected the survival of the species.

Thus, natural selection is the correct answer.
