    The correct answer is option d, that is, missense mutation.

    Explanation:

    A missense mutation is a kind of nonsynonymous substitution. In this form of mutation, a modification in a solitary nucleotide takes place that results in the formation of a codon that codes for a distinct amino acid. In this mutation, a change in DNA nucleotide results in the administration of a different amino acid within a protein. Though the mutation is not that harmful, however, it can slow down the working of a specific protein.
