Artificial selection is the process where humans intentionally breed plants or animals for desired traits. In this case, selecting cows that produce more milk involves humans intentionally breeding cows to have certain desirable traits, making it an example of artificial selection.

Option A is an example of natural selection because the pests that are resistant to pesticides survive and reproduce, passing on their resistance to their offspring.

Option B is also an example of natural selection because the weeds that are able to survive in the presence of herbicides will reproduce and pass on their genes to their offspring.

Option D is not an example of artificial selection because humans do not intentionally breed insects to transmit disease more efficiently. Instead, this could be an example of natural selection or adaptation as the insects that are better at transmitting the disease will survive and reproduce, passing on their genes to their offspring.
