What this question is about
A frame of reference in which Newton's Law of Inertia is obeyed is called
(A) an inertial reference frame. --- Yes.
A frame in which the Law of Inertia holds.
Questions

A frame of reference in which Newton's Law of Inertia is obeyed is called
(B) a proper reference frame. --- No.
It is the proper frame for the other laws
but that's not what it is called.

A frame of reference in which Newton's Law of Inertia is obeyed is called
(C) an equilibrium reference frame. --- No.
The First Law does not deal with
equilibrium.

A frame of reference in which Newton's Law of Inertia is obeyed is called
(D) a non-fictitious reference frame. --- No.
But frames in which it is not obeyed
can have fictitious forces.
