Name all segments parallel to ZS. VZ SW OR WZ
Answer: none of the above
Assuming S is at the bottom of the image, ZS isn't even drawn, and even if it was there aren't any other pair of points forming a parallel line with it.
I'm guessing this is a typo. Let's just go through the list and see what's parallel to what.
VZ) Parallel to SW, UY, TX
SW) same list, VZ, UY, TZ
WZ) parallel to VS
