(C) The genetic code is read in groups of three bases,known as codons. If one or two bases are added or deleted,it causes a frameshift mutation,which alters the entire reading frame of the mRNA sequence downstream of the mutation. However,if three bases (or a multiple of three) are added or deleted,the reading frame remains intact because the addition or deletion of a full codon does not shift the grouping of the subsequent nucleotides. Therefore,the addition or deletion of $3$ bases (or multiples of $3$) does not change the reading frame.
