It is a scientific law
Explanation:
A scientific law states a constant relationship between two or more variables, each of which represents a property or measurement of specific systems. It is a constant and unchanging rule, usually expressed mathematically which allows to predict the unknown based on what is known with logical and real relationships.
A scientific theory is a set of concepts and rules (scientific laws) that express the relationships between observations of such concepts and generates a principle or set of principles to explain a phenomenon.

Answer:
Option B, Snakes and lizards share a common ancestor.
Explanation:
From the description provided, it is clear that both the lizard and snake (including pythons) have evolved from the same ancestors which had hind legs. Since both the organism (i.e lizard and snake) underwent evolution (differently) for million of years such that the hind legs in lizard are visible and used even today but the hind legs in snakes are buried in muscles toward their tail ends and are not used. Such features which are not used at all or are poorly used are called as vestigial organs.
Hence, option B is correct
Answer:
If the moon has grown to twice its size, the gravitational force of the Earth on the Moon would be twice as much
Explanation:
The force of gravity between two objects is doubled if the mass of one of the objects is doubled.
If the moon has grown to twice its size, the gravitational force of the Earth on the Moon would be twice as much, since the gravitational force is proportional to the masses of both the Earth and the Moon.
