Assuming that other civilizations exist in the Milky Way Galaxy, it is highly likely that they are far more technologically advanced than we are because the universe has been around for billions of years longer than Earth, and other civilizations could have evolved and developed technology much earlier than we have. However, it is impossible to predict societal structures or physical attributes of extraterrestrial life with any certainty. Option A is a common stereotype perpetuated by pop culture, and there is no evidence to support it. Option C is also unlikely because societal structures are often shaped by environmental and historical factors unique to a planet and species. Option D assumes that biomorphic aliens exist, which is not a given.
