Answer 2

D. Newton

Explanation:

Sir Isaac Newton discovered gravity when he observed an apple falling from its tree. He wanted to know what made it fall to the ground, and discovered that the gravitation force exerted by the Earth makes any object on Earth to be attracted towards the Earth's surface.

The gravitational force is a force that attracts any object with mass. Newton's law of universal gravitation is usually stated that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Option D is the answer.
