A frame of reference has four coordinates, x, y, z, and t is referred to as the_____________

A. Inertial frame of reference

B. Non-inertial frame of reference

C. Space-time reference

D. Four-dimensional plane

I got this question in an online interview.

The doubt is from Einstein’s Special Theory of Relativity in portion Ultrasonics & Relativity of Engineering Physics I

Right answer is C. Space-time reference
