NEET Biology question

Assertion: Genetic drift refers to changes in allele frequency occurring by chance. Reason: Sampling errors often lead to the elimination of certain alleles and the fixation of others, reducing genetic variability.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True
