Okay everyone, it seems to be that you guys really aren't paying any attention to the whole question.Dear friends, the question says that we have to decide the odd one out on the basis of composition(on what it is made of), not anything else.If you see it this way, Jupiter is the odd one out, not Earth,Venus or Mars, because it is the only planet made of gases, mostly hydrogen. All the other ones are rocky or terrestrial planets, made mostly of rocks and metals, molten or solid.
