Solution
The correct option is B 2
Earth was formed when a swirling mass of gases, under the effect of gravity condensed in space, which happened approximately 4.5 billion years ago.
After the big bang explosion, temperature decreased leading to the formation of hydrogen and helium gases.
The big bang is a single huge explosion leading to the formation of the Universe, which is about 20 billion years old.
When Earth was formed its surface was covered with a molten mass from which water vapour, methane, ammonia, and carbon dioxide were released.
Thus, the second and third statements are incorrect.
