(C) molecular probe is a fragment of $DNA$ or $RNA$ of variable length (usually $100-1000$ nucleotides long) which is used in $DNA$ or $RNA$ samples to detect the presence of nucleotide sequences that are complementary to the sequence in the probe.Key characteristics of a molecular probe include:$1$. It is a short chain of nucleic acid $(IV)$.$2$. It is typically single-stranded $(III)$ to allow hybridization with the target sequence.Therefore,the correct combination is $III$ and $IV$.

Choose the correct option for a molecular probe.
$I -$ Long chain of nucleic acid
$II -$ Double-stranded
$III -$ Single-stranded
$IV -$ Short chain of nucleic acid
