Answer:

C. It formed the Great Lakes.

Explanation:

    At the height of the last Ice Age, some 20,000 years ago, ice sheets in the northern hemisphere (Eurasia at the top, North America at the bottom) covered the largest area of the territory now known as North America. Scientists believe that the formation of the five Great Lakes was influenced by the movement of ice during the latest ice age.
