Which statement about the development of Newton's theory of universal gravitation is correct

Newton's theory of universal gravitation, formulated in the late 17th century, posits that every mass attracts every other mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

A correct statement about the development of Newton's theory is:

"Newton's theory of universal gravitation was influenced by earlier work in astronomy and physics, including the observations of planetary motion by Johannes Kepler and the mathematical principles developed by Galileo Galilei."

This statement highlights the interdisciplinary nature of Newton's work, as he built upon the contributions of earlier scientists to formulate a comprehensive theory of gravitation.
