There are about a hundred theories that claim to explain the origin of the universe. However, there are only three fundamental theories and all the other theories can be derived from one of these. Big Bang Theory, which is by far the most widely believed theory in the science fraternity, has about thirty corollaries that differ among themselves in minute details. The rest of the theories such as the String Theory and the Time's Arrow Theory, although very widely different in their ideas and explanations, can be derived from one of the other two fundamental theories.

Which one of the following can be inferred from the passage?

a. Big Bang Theory, String Theory, and Time's Arrow Theory are the fundamental theories around which all other theories revolve.

b. String Theory and Time's Arrow Theory are not derived from the same parent theory.

c. All the theories explaining the origins of life revolve around the same three fundamental theories.

d. Any new theory about the origin of the universe has to conform to one of the fundamental theories.

e. Big Bang Theory is fundamentally different from the parent theories that can derive the String Theory or the Time's Arrow Theory.
