B) floating on the surface of a layer of liquid metallic hydrogen
C) high in the atmosphere where it could collect solar radiation
D) at the center, close to the rocky core where a rocky surface exists

Quizplus · Accepted Answer

Uranus and Neptune are known as ice giants, with the vast majority of their mass being composed of water, ammonia, and methane ices. Therefore, any life existing there is most likely to be found in the oceans of liquid ices beneath the surface where there may be enough energy to support life. Life floating on a surface layer of liquid metallic hydrogen (B) or high in the atmosphere (C) would be unlikely due to the harsh and inhospitable conditions in those environments. Additionally, there is no evidence to suggest that there is a rocky surface at the center of Uranus or Neptune, making option D unlikely.
