Class : Class 6
The answer should be A. I understand what you are saying but look they told that the planets C and D are gases. They did not asked how big they are but they asked are they made up of gases. So the answer should be A since C is the largest.

Ans 2:

Adit Aggarwal from Vibgyor High, Bengaluru
Class : Class 5
Planet D is Uranus which is mostly rocky and icy. I do not understand why it is not A and D. someone please clarify.

Ans 3:

lavanya from bcm chd road, Ludhiana
