Newton discovered the gravity is the universal as said in D. But D . It is unique law to the whole universe. So it is the universal law of gravitation.

Gravity is the fundamental force of attraction between  bodies . Simply between two isolated bodies separated by a distance by , the force of agravitational attraction is proportional to the product of their masses and inversely proportional to the square of the distance.

The correct choice is D.

Some of the options provided are completely false, others are true, but were not discovered by Newton.  Newton's discovery was D, that gravity is a universal phenomenon.

While it is true that all objects on Earth fall at the same rate of acceleration (or they would if there were no resistance from the atmosphere that would act differently on objects of different shapes), this was known before Newton's day.

Newton's insight was that the force that made things fall on Earth was also what made the moon orbit.  This meant that the force was not confined to the Earth.
