Why is it likely that life, should it exist elsewhere in the universe than just

Question

Why is it likely that life, should it exist elsewhere in the universe than just on Earth, would be based on carbon chemistry?

A: Carbon combines more readily than other atoms with nitrogen, the major component of atmospheres such as that of Earth, to produce complex molecules

B: Carbon releases more energy than do most other atoms when it combines with oxygen, providing the energy for life processes in living organisms

C: Carbon is expected to be far more abundant than silicon or other like elements that can combine to produce complex molecules

D: Carbon can bond with many more atomic species in a wider variety of complex forms than other equivalent elements, such as silicon

Explanation / Answer

The answer is D

The main reason behind this is that carbon has the ability to form bonding with many more species of atoms ain wide variety of ways. That is the reason why we can form millions and millions of organic molecules for which carbon is the base atom.
