You would need more than natural phenomena for a scientific theory because a theory is a proposed explanation whose status is still conjectural and subject to experimentation, in contrast to well-established propositions that are regarded as reporting matters of actual fact.
Answer:
c.Both the mass of the objects and the distance between them
Explanation:
The Law of Universal Gravitation states that the force of gravitational pull between objects is directly proportional to the product of the mass of both objects and indirectly proportional to the square of the distance between them.
This means that as the product of the masses increases, the force increases. On the other hand, as the distance between the objects increases, the force decreases.
It can be computed with the formula:

Where:
F = Gravitational force
M₁ = Mass of object 1
M₂ = Mass of object 2
r = distance between the center of the masses
G = gravitational constant (this is a fixed number so the pull is not dependent on this)
If atoms share two , three or more pairs of electrons..they are covalent bonds..for example, methane
if the atoms share only a lone pair of electron contributed by only one of the combining atoms but shared by both ..then it is a coordinate bond ..for example, ammonium ion
