The idea of inflation makes one clear prediction that,until the discovery of an accelerating expansion,seemed to contradict the available observations.What is this prediction?
A)Inflation predicts that the early universe should have regions of enhanced density that could have acted as "seeds" for the formation of galaxies and large structures.
B)The universe should be geometrically "flat" (in the four dimensions of spacetime).
C)Inflation predicts that the temperature of the cosmic microwave background should be almost (but not exactly)the same everywhere.
D)Inflation predicts that the entire universe must be far larger than the observable universe.

This was a key prediction that seemed at odds with observations until the discovery of the universe's accelerating expansion, which provided supporting evidence for the theory.
