As we have already studied in types of Mutations -

Frame-Shift Mutation:

  • There is another category of the point mutation in which the normal reading frame of the base triplet [codon] is changed. Such mutations are known as frameshift mutations. 
  • In these mutations, the normal reading frame of base triplets [codons] is altered due to the addition or deletion of a single base pair of nucleotides in mRNA.

Hence, the correct option is (b).
