Why did you ask that question if you know the answer

The two kinds of glaciers are called A. continental and valley.

There are also other types such as tidewater, outlet, piedmont, etc. but continental and valley glaciers are among the most widely-spread ones. The other options do not refer to glaciers at all, but rather to other types of formations on Earth.
