Comparing the Clouds of Earth and Venus,we Find That

Comparing the clouds of Earth and Venus,we find that:

A) both are made chiefly of water vapor.
B) ours lie in the troposphere, within 10 kilometer of our surface, but Venus has a higher troposphere, with its clouds about 40 kilometers high.
C) like ours, they rotate around Venus slower than Venus rotates on its axis.
D) Venus has much more carbon dioxide, so dry ice clouds dominate.
E) Venus is too hot for clouds to form, so we see only a barren world telescopically.
