It should be "old gibbous" as in 15 days "no moon" becomes "full moon". The "new crescent moon" is a stage after no moon ,so in 15 days it will become a stage after new moon which is old gibbous.

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.

it is jupiter because it says that choose the odd one out on the basis of composition which means we have to choose the odd one out on the basis of what they are made up of as earth , venus and mars are rocky planet whereas jupiteris a gaseous planet so it is D

Ans 14:

Class : Class 4

Ans 29:

Class : Class 5
only earth consists of water

Ans 30:

Class : Class 6
Actually, Jupiter is the right answer. They asked us to find the odd one out in terms of composition or what they are made up of. Since Jupiter is a gas giant with mostly hydrogen and Earth,Venus and mars are rocky planets with many valuable elements, the answer is D.

Ans 31:

Class : Class 4
it can be B [VENUS] BECAUSE IT HAS NO MOONS

It can be D because Jupiter is the largest planet .

Ans 44:

Class : Class 4
It can Be A-only red planet, B-rotates anti-clockwise, C-only planet with life, D-largest planet and has hydrogen gas. So it could be all of them

Ans 45:

Class : Class 6
It can be B,C and D because Venus does not have any moon and spins anti-clockwise, Earth is the only planet we live and Jupiter because it is a gas giant and is the more than 10 moons.

Ans 46:

Class : Class 9
It can be Venus also because it rotates in anti-clockwise direction.
