C (Point mutation)

Explanation:

Mutation is any change, no matter the degree or size, that occurs in a nucleotide sequence of a DNA. It occurs naturally due to mistakes during replication or can be induced by mutagens (mutation-causing components). A mutation is regarded to be POINT MUTATION, if it affects only a single nucleotide in the sequence.

Point mutation occurs in scenarios whereby a single base pair/nucleotide is substituted/replaced, deleted/removed from the sequence, or inserted/added. This sorts of mutation can yield beneficial or harmful effect in the organisms they occur.
