Solution

The correct option is C SNP
  • DNA polymorphism can be defined as a condition where more than one different nucleotide sequence can exist at the same locus in DNA.
  • A single nucleotide polymorphism (SNP) is a variation in which a single nucleotide (A, T, C or G) differs between members of the same or different biological species.
  • This type of polymorphism may be due to a single nucleotide mutation like the substitution of the nucleotide base by another base.
Thus, the correct answer is option C.
