Q.

Which of the following is an alternative theory to the Big Bang theory developed in 1948, stating that the universe does not change even though it is expanding over time?
Explanation:

ANS. (B) 
The Steady State theory (also known as the Infinite Universe theory or continuous creation) was developed in 1948 by Fred Hoyle, Thomas Gold, Hermann Bondi and others as an alternative to the Big Bang theory. In the steady-state theory, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter. It asserts that the observable universe is basically the same at any time as well as at any place.
