Identify which statement represents a scientific law. a) all matter is comprised of atoms. b) the earth is older than 100,000 years. c) force equals mass times acceleration. d) the universe was created at the big bang.

C!! a law cannot be changed!

The correct answer will be option-C.

Explanation:

A scientific law is a statement which provides a description of the natural phenomenon.  A law can be quantified as it provides the data and holds true everywhere.

In the given question, an option which represents a force in terms of mass and acceleration represents a description of how a force can be related to these other units. Also, it holds true everywhere as it cannot change.

Thus, Option-C is the correct answer.
