For U = {q, r, s, t, u, v, w, x, y, z}

A = {q, s, u, w, y}
B = {q, s, y, z}
C = {v, w, x, y, z}
identify the following.
5) C
A) {v, w, x, y, z}
B) {q, r, s, t, u}
C) { }
D) {v, z}

To identify the set C, we need to compare the elements in set C with the elements in the universal set U.

Here are the steps to identify the set C:

1) Write down the elements of set C: {v, w, x, y, z}.

2) Compare each element in set C with the elements in the universal set U.

- v: v is an element of set C.
- w: w is an element of set C.
- x: x is an element of set C.
- y: y is an element of set C.
- z: z is an element of set C.

3) Based on the comparison, we can conclude that all the elements in set C are also elements of the universal set U.

So, the correct answer is:

A) {v, w, x, y, z}
