Ans 5:

gautam from GIIS KL, Kuala Lumpur
Class : Class 5
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.
