Earth is known as the blue planet because of its extensive oceans that give it a predominantly blue appearance when viewed from space. The reflection of sunlight off the oceans contributes to its blueness.
It depends a bit on what the question means. Sometimes Earth is called the blue planet because it looks mainly blue, because of the oceans. Also, Neptune is blue because of the methane in its atmosphere. Uranus is a bluish green colour too. Overall, I think "Neptune" is the best answer.
