A theory is a reasonable explanation of the phenomena observed in nature, with much evidence to support it (option C).

Explanation:

A theory gathers a set of hypotheses that can be demonstrated and constituted on a scientific basis, until they are questioned by other evidence.

To construct a theory, the processes of observation, deduction and investigation must be thorough, but leave open the possibility of being discussed and refuted in the absence of definitive arguments.

A theory becomes law when it has been proven beyond a doubt.
