$DNA$ fingerprinting technique was discovered by

Read the following statements:
$A.$ Variation at genetic level arises due to mutations.
$B.$ The technique of $DNA$ fingerprinting was initially developed by Alec Jeffreys.

$A$: Unknown $DNA$ after hybridization with $VNTR$ probe,the autoradiogram gives many bands of differing sizes in $DNA$ profiling.
$R$: These bands represent the $DNA$ fingerprint of the organism.

Select the option that shows the correct sequence of the $DNA$ fingerprinting process.
$(i)$ Isolation of $DNA$
$(ii)$ Hybridization using labeled $VNTR$ probe
$(iii)$ Transfer of $DNA$ fragments to nylon membrane
$(iv)$ Separation of $DNA$ fragments by electrophoresis
$(v)$ Autoradiography
$(vi)$ Digestion of $DNA$ by restriction endonucleases

Who developed $DNA$ fingerprinting?

Alec Jeffreys used $ . . . . . . $ as a genetic marker.
