Venus and mercury has 0 moons ,mars has 2 moons not Venus and Jupiter ,Uranus,Neptune and Saturn also have more than one moon. So, d is correct. There is iron oxide in Mars' soil and there are also rust particles in the soil.These components get kicked around in the air of Mars by weather and wind making it look red. So, c is also correct. Neptune appears bluish in color due to the presence of helium gas. The above statement is also correct. Even though Jupiter is the largest planet in the Solar System, it is one of the fastest rotating planets. So,option A is incorrect and because of that it is the answer.

Dishita Santosh Walujkar from Nutan English School, Kurduwadi
Class : Class 7
right answer is C

Ans 2:

Vivaan A V from Loyola school, Jamshedpur
Class : Class 4
The right answer is "B" because not all containers (such as beaker and test tube) are waterproof. They may leave some remnants. So, they may leave a few ML of the liquid in them; and that is crucial. You cannot say that they have the same volume; even if they are a microliter lesser. It will reduce the volume more/less according to how much is left behind.
