Without the presence of nebular gas, ice-rich planetesimals would not be able to gather hydrogen and helium to become gas giants. This would likely result in the absence of gas giants in the planetary system, or they would be much smaller than those found in systems where the gas is not quickly disbursed. The other choices are not necessarily true outcomes of a quickly disbursing nebular gas cloud.
