Why did the giant planets grow larger than the terrestrial planets? because there was more solid ice farther from the sun. b. because there was more metal farther away from the sun. c. because there was more rock farther from the sun. d. because there was more gas farther from the sun.

D. Because there was more gas farther from the Sun. As the are out of the range

Explanation:

Basically, due to the core acceleration mechanism, theory to the formation of gaseous objects that can pull the gas as farther away from the sun the impact of solar winds is quite less. There are low-pressure regions Unlike rocky planets that have a different atmosphere and gas giants don't have a well-defined surface there atmosphere simply becomes denser to the core which may also be in a liquid-like state thus not suitable for landing. There are four gaseous giants in our solar system such as Uranus, Neptune, Jupiter Saturn all have atmosphere covered with ice or gases and all are bigger as compared to terrestrial planets like earth thus they are called as Jovian planets.  These Jovians attract large amounts of gas as their magnetic fields are stronger and huge size ad gas giants are known as metallic molecules of hydrogen and helium in core consisting of more than 50% of the planet masses.
