Q. Assertion: Satellite DNA forms the basis of DNA fingerprinting. Reason: DNA from every tissue shows same degree of polymorphism.

A) Both assertion and reason are true and reason is the correct explanation of assertion.
B) Both assertion and reason are true but reason is not correct explanation of assertion.
C) Assertion is true, but reason is false.
D) Both assertion and reason are false.
