Well, B and C are correct. Now on A, it seems to me that the Sun is the principal source of Energy on Earth, however, I am not certain what the answer writer had in mind when she wrote "on Earth". If she meant energy produced on Earth, then that will not include the Sunlight....in that case, answer d. So I dunno.
