Find the indicated intersection or union.

Question

{q, s, u, v, w, x, y, z}*{q, s, y, z}
I think its C. Any feedback is appreciated!

A) {s, u, w}
B) {v, x}
C) {q, s, u, v, w, x, y, z}
D) {s, u, v, w, x, z}
E) None of the above

the intersection set is {q,s,y,z) , the elements belonging to both
and the
union set is {(q,s,u, v,w,x,y,z}, the elements found in either one or the other. Would the right one be Choice "C"? Thanks!
