Imagine a population of moths. White moths are easier for birds to see and eat. Gray moths blend into their surroundings, so they are less visible to birds than white moths. As a result, gray moths are more likely to survive and reproduce, enabling the gene for gray coloration to be passed on to the next generation. This increases the frequency of genes for gray coloration in the population. Which evolutionary process does this scenario describe?

Answer: Natural section

Explanation:

This is natural selection through directional selection, because the frequencies of gray allele traits for selection is higher than the white. Therefore; they were more fitted in the population, to withstand the selective pressure; birds and subsequently passed these traits down to their offspring.
