The history of Sir Isaac Newton's study of gravity does which of the following?

A. Illustrates how a theory becomes a law

B. Provides an example of a theory that has been discredited

C. Demonstrates the importance of gravity in marine science

D. Shows that theories have long been an important part of science

A. Illustrates how a theory becomes a law

A. Illustrates how a theory becomes a law

Explanation:

Newtons studied about the gravity for a very long time and proposed theory about it.

Later on, based on his theories comes the gravitational law. His theory were based on various assumptions and examples that he related to explain the structure of universe.

His work shows how theories can become laws which are universally obeyed.
