Which technique is used to identify the binding of a radioactive probe with its complementary $DNA$ in a clone of cells?

Repetitive sequences are stretches of $DNA$ with repeated bases many times in a genome, but
$(a)$ These sequences are of no transcriptional function
$(b)$ These are associated with euchromatin region
$(c)$ These help to identify a person on the basis of their $DNA$ specificity

$DNA$ fingerprinting technology was discovered by Alec Jeffreys and this technology uses:

Mark the correct one (w.r.t. application of $DNA$ fingerprinting).

Arrange the following steps of $DNA$ fingerprinting in a correct sequence.
$A$. Isolation of $DNA$ and its digestion by restriction endonucleases.
$B$. Hybridisation using a labelled $VNTR$ probe.
$C$. Transferring of separated $DNA$ fragments to synthetic membranes.
$D$. Detection of hybridised $DNA$ fragments by autoradiography.
$E$. Separation of $DNA$ fragments by electrophoresis.
