What do we mean when we say that there is a "Consilience of Evidence" supporting a theory?
Gnoma [55]

The correct answer is C) That scientists who have worked on the theory have independently and repeatedly come to the same conclusions over time.

Explanation:

In science, the term "consilience of evidence" is used when the evidence of a hypothesis or theory is consistent especially evidence from independent scientists or sources. This often implies the theory has been tested many times and by different experts and even using different methods but the results are always the same. This consilience of evidence is essential to declare a theory as valid and concluding. In this context, the option that describes the meaning of this term is C.
