The correct answer is:
C) it leaches nutrients out of plants.
Acid rain droplets or acid fog comes in contact with tree leaves or tree needles. It can then leach out important tree nutrients from the leaves or needles. Specifically, acid rain removes calcium, potassium, and magnesium from the tree. These are nutrients that the tree needs for growth and reproduction. This happens because these important nutrients are bases, and opposites attract—so the base plant nutrients are drawn out of the trees by their attraction for the acid droplets that fall on them.
