The correct answer is option C, dense, hot, supermassive ball
As per the big bang theory, the Universe is believed to be originated from something which was infinitely small, hot and dense. Since the big bang theory or the massive explosion that took place billions of years ago, the universe till date is in the process of expansion and cooling. The supporting logics of big bang theory are as follows –
a) The Hubble’s law – This law states that the galaxies are continuously moving away from each other
b) The discovery of Cosmic Microwave Background radiation (-454.765 degree Fahrenheit, -270.425 degree Celsius) supported the logic of universe being extremely hot before the big bang theory
c) The abundance of the "light elements" Hydrogen and Helium supported the logic of universe being extremely dense
