Answer 1

Answer: (A), (B), (C)

Even a single nucleotide substitution can be termed mutation.

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Gene mutations lead to creation of new alleles and thus different traits.
