Answer:
The correct answer - The Gas giants are much much larger in size.
Step-by-step explanation:
There are two distinct types of planets that are four rocky planets and four gas giants plants. Mercury, Venus, Earth, and Mars are four rocky planets, and Neptune, Uranus, Saturn, and Jupiter are four gas giants.
The Gas giants plants are much much larger in size in comparison to the rocky planets. It is because rocky planets have relatively low gravity than gas giants and were not able to attract large amounts of gas to their atmospheres.
Thus, the correct answer - The Gas giants are much much larger in size.
