    Answer:

    B. a process by which one of the extreme variations of a trait is favored

    Explanation:

    The graph for this type of selection looks sort of like a camel’s hump. With that being said, the phenotype of a population experiencing directional selection goes from one extreme to the other. Reference the evolution of the peppered moth during the Industrial Age as an example.

    Sincerely hope this helps! God bless!
