Since $\overrightarrow{P} \times \overrightarrow{Q}$ is a vector normal to the plane containing the vectors $\overrightarrow{P}$ and $\overrightarrow{Q}$ and $(\overrightarrow{P}+\overrightarrow{Q})$ lies in the same plane, the angle between $\overrightarrow{P} \times \overrightarrow{Q}$ and $\overrightarrow{P}+\overrightarrow{Q}$ is $90^{\circ}$
Hence C is the correct answer.
