Solution

The correct option is B Shows high degree of polymorphism in population and also the same degree of polymorphism in an individual, which is heritable from parents to children.
Satellite DNA
Satellite DNA is a highly repetitive, non-coding DNA sequence that forms the primary structural constituent of heterochromatin.

Importance of satellite DNA
Satellite DNA has the following importance:
● These DNA sequences are unique to an organism.
● It shows a high degree of polymorphism which can be inherited from parents to offspring.
● VNTR (Variable Number Tandem Repeats) are mini-satellite DNA which is used in DNA fingerprinting.

Final answer
(A) Shows high degree of polymorphism in population and also the same degree of polymorphism in an individual, which is heritable from parents to children.
