a. Disruptive selection

Explanation:

Imagine there is a population of  red-colored, white colored,  and green colored wings butterflies on  a red- petals, green leaves hibiscus flower plants.

Generally the  red-colored wings will be camouflaged by the red-colored  hibiscus flower petals, while the green color of the leaves will masked the green colored butterflies.Therefore the white-colored butterflies will be exposed to predators and therefore selected against by environmental pressure leading to disruptive selection.

Consequently in the  butterfly population,  there is  increased genetic variation in  red and green butterflies population ,  with consequent population diverse.

Therefore when an extreme value for a trait(red and green wings colors) is  favoured for intermediate trait (white).The term that describes this is called Disruptive selection. One of the naturally selected  wings may  migrate from the population leading to speciation.
