$ii.\ $Four rays.
$iii.\ $Two non$-$intersecting line segments.
Answer
This is because it has two end point $P$ and $R.$
$\overline{\text{QS}}$
This is because it has two end point $Q$ and $S.$
$\overline{\text{PQ}}$
This is because it has two end point $P$ and $Q.$
$\overline{\text{RS}}$
This is because it has two end point $R$ and $S.$
$ii.\ $Rays are:
$\overrightarrow{\text{PA}}$
This is because it has only one end point $P.$
$\overrightarrow{\text{RB}}$
This is because it has only one end point $R.$
$\overrightarrow{\text{QC}}$
This is because it has only one end point $Q.$
$\overrightarrow{\text{SD}}$
This is because it has only one end point $S.$
$iii.\ \overline{\text{PR}}$ and $\overline{\text{QS}}$ are the two non-intersecting line segments as they do not have any point in common.
