$DNA$ polymorphism forms the basis of:

What is the basis of $DNA$ fingerprinting?

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

Given below are two statements.
Statement $I$ - In the population,every person shows unusual sequences of $20-100$ base pairs,which are repeated several times and are termed as $VNTRs$.
Statement $II$ - $VNTRs$ are same in each individual and hence is the key factor in $DNA$ profiling.
In the light of above statements,select the correct option given below:

Would it be appropriate to use $DNA$ probes such as $VNTR$ in $DNA$ fingerprinting of a bacteriophage?

Satellite $DNA$ is important because it .........
