    Option C is the correct answer.

    Explanation:

    Mutation: Mutation is defined as a heritable change in the sequence of DNA of an organism, and the resulting species known as mutant. A change in DNA sequence is extended to mRNA through the process of transcription, and cause to alter sequence of amino acid in a protein on translation process.

    So, If a mutated DNA sequence produces a protein that differs in one, central amino acid from the normal protein is cause an addition mutation and a deletion mutation. It means may addition of one or more bases, or may removal of one or more bases in amino acid sequence.
