Answer:
Option A, GV law
Explanation: The laws of gravity (actually called "Newton's Law of Universal Gravitation") are laws in the field of classical mechanics that tell us the behavior of gravity.
now the simplifications are:
a) GV Law
This is fine because with this method you will always remember that these are laws.
b) L of G
This could mean different things, it is not advisable to use this type of abbreviations, since you can read it and not remember what L or G means.
c) VGlity
I really don't understand what this means, this is not a good option.
d) Newt gravity.
This option is also good because you can remember Newton's name, but it is a bit longer than the first option.
So, the option that has more information and is also shorter is the first option of the GV law, so that would be the correct option
