To solve the problem, we need to follow these steps:
- Compute the union of sets \(A\) and \(B\).
- Find the complement of the union of \(A\) and \(B\) with respect to the universal set \(U\).
- Compute the intersection of set \(C\) with the complement obtained in step 2.
- Write the result in roster form.
First, we find the union of sets \(A\) and \(B\):
\[
A \cup B = \{f, g, p, x\} \cup \{g, h, x, y\} = \{f, g, p, x, y, h\}
\]
Next, we find the complement of \(A \cup B\) with respect to the universal set \(U\):
\[
(A \cup B)^{\prime} = U \setminus (A \cup B) = \{f, g, h, p, q, r, x, y, z\} \setminus \{f, g, p, x, y, h\} = \{q, z, r\}
\]
Finally, we compute the intersection of set \(C\) with the complement of \(A \cup B\):
\[
C \cap (A \cup B)^{\prime} = \{p, r, x, y, z\} \cap \{q, z, r\} = \{z, r\}
\]
