Answer: Option B

Solution(By Examveda Team)

The sudden change in the DNA sequence is Mutation.
A mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA.
The mutation is the ultimate source of all genetic variation, providing the raw material on which evolutionary forces such as natural selection can act.
