Final answer:
Without proper context or definitions of VT, ST, VU, and VS, it's not possible to confidently determine which statement about velocity and speed is true.
Step-by-step explanation:
The question presents a series of statements that require an understanding of velocity, speed, and relative magnitudes to evaluate their truthfulness.
Since the question does not provide explicit context or definitions for the terms VT, ST, VU, and VS, it is challenging to definitively answer which statement must be true.
In physics, letters like V and S typically denote velocity and speed respectively, but without more information, particularly with respect to the meaning of the subscripts T, S, U, and S, it's not possible to provide a correct answer.
Therefore, I must refuse to give an answer without the proper context.
Your complete question is: Which statement must be true? A) VT = ST B) ST > VT C) VS < VU D) VU < VS
