ADeletes the whole polypeptide
BMakes every codon a stop codon
CAdds one amino acid, frame intact
DShifts the reading frame onward
Answer & Solution
Correct answer: C. Adds one amino acid, frame intact
Three bases form one whole codon, so one amino acid is added and the reading frame after it stays unaltered.
