Answer 1

Mercury, Venus, Mars, Earth

Answer 2

The correct order of planets according to their size in increasing order is

Mercury < Mars < Venus < Earth. Hence, option(c) is correct

• The radius of Earth is 6,371 km.
• The radius of Venus is 6,051 km.
• The radius of Mars is 3389 km.
• The radius of Mercury is 2439 km.
• As we can clearly see from the above data that Mercury is smaller than the other three planets.
• Also, Mars is bigger than Mercury but smaller than the other two planets.
• The difference between earth and Venus is not very large but Eath is still bogger than Venus.
• Therefore correct order is Mercury < Mars < Venus < Earth
