“all matter is made up of atoms that are in continuous, random motion.” the statement above is an example of a law because it is a factual statement about how something behaves. theory because it is a well-tested, widely accepted explanation. law because it cannot be modified based on new information. theory because it cannot predict what may happen in the future.

The matter is known to be made up of  the atoms that are continuously in motion in a random manner. This statement is a theory as it has been well-tested and widely accepted explanation. The knowledge that the atoms are continuously moving inside the matter explains a lot of properties exhibited by the matter and has been tested, and thus, accepted universally.

Hence, the correct answer is 'theory because it is well-tested and widely accepted explanation'.
