This is a random error/change in the dna sequence. these may be inherited or occur in cells during the lifetime of the organism.
a. genetic drift
b. migration
c. mutation
d. natural selection

C.Mutation

Explanation:

Genetic mutation is the change that alters the nucleotide sequence of DNA. These mutations in the DNA sequence can carry out the substitution of the amino acids in the resulting proteins. A change in a single amino acid may not be important if it is conservative and occurs outside the active site of the protein. Otherwise it can have severe consequences.

For example, Prader-Willi syndrome is a rare disease caused by a mutation of DNA in the proximal area of the long arm of chromosome 15 (15q11-q13).
