Hey, the answer is C. Can anyone explain?

hi the correct answer is C. because this mutation would cause a change in the DNA of the person’s cells . and we know DNA is the template for mRNA synthesis through transcription so mutation would be transcribed in to mRNA. than during translation the altered mRNA would incorporate a different amino acid in to the growing polypeptide chain . D is for multiple mutations but the question specifies the fact that its on the same base pair so only one mutation.
