I think the correct answer from the choices listed above is option C. The substitution, addition, or removal of a single nucleotide in DNA is called a point mutation. It is a type of mutation that affects only one or very few nucleotides in a gene sequence.

Answer : The correct answer for the blank is -  C) point mutation.

Mutation can be described as the permanent change in the sequence of genetic material (that is DNA) of living organisms.

Point mutation corresponds to change in one nucleotide sequence of DNA.

There can be primarily three types of point mutation that is deletion (one nucleotide is deleted from the sequence), addition (a nucleotide is added), and substitution (a nucleotide is substituted by another nucleotide).

Thus, option C) is the right answer.
