Present day glaciers are found primarily in
a. canada and greenland
b. canada and iceland
c. antarctica and greenland
d. antarctica and iceland

The correct answer is - c. Antarctica and Greenland.

Most of the glaciers nowadays, or an estimated 275,500 square kilometers of them, are found in Antarctica and Greenland. These two places have by far more glaciers than any other place in the world where glaciers are scarce and every year their number is reducing. Both Antarctica and Greenland are places with constant winters that occupies almost all their respective territories, only the shoreline of Greenland is less extreme and just few spots on the shores of Antarctica. They are both pretty high and have the proper angle so that the glaciers can slowly move downwards towards the seas.

all three options are correct
