उत्तर

Which type of selection explains industrial melanism observed in moth, Biston bitularia directional.

Explanation:

During industrial pollution, dark-colored (melanic) moths had a selective advantage due to camouflage on soot-darkened trees, leading to an increase in their population. This directional change in phenotype frequency towards the darker form illustrates directional selection responding to environmental changes caused by industrialization.
