Step2: Analyze each option

• For $\overrightarrow{OS}$ and $\overrightarrow{QU}$, they do not meet.
• For $\overrightarrow{TU}$ and $\overrightarrow{NO}$, they do not meet.
• For $\overrightarrow{RS}$ and $\overrightarrow{QU}$, they do not meet.
• For $\overrightarrow{PQ}$ and $\overrightarrow{NQ}$, they meet at point $Q$.
