Correct choices: rapidly cooling protogalactic clouds and rapidly spinning protogalactic clouds.
Reason: spirals form when a protogalactic cloud retains angular momentum and cools efficiently so gas can settle into a rotating disk and form stars gradually. Major collisions/mergers and very high initial densities tend to destroy disks or produce rapid starbursts, leading instead to ellipticals or disturbed/irregular systems.
