Concept:The shaded part is the region inside $R$ that lies outside $P$.Explanation:The shaded portion lies completely within set $R$, so it must satisfy $x \in R$.It does not lie within set $P$, so it belongs to the complement of $P$, written as $P^{1}$.Hence, the common area between $P^{1}$ and $R$ is required.There is no restriction involving $Q$ in the shaded portion.So the required shaded region is the intersection $P^{1} \cap R$.Answer:Option C: $P^{1} \cap R$
