Answer:
<em>The correct option is B) Missense mutation.</em>
Explanation:
A missense mutation can be described as a type of point mutation in which a mutation in a single nucleotide causes the codon to change and form a different type of amino acid. As in the above scenario, we can see that the code CAU coded for the amino acid, Histidine, before a point mutation occurred. After the point mutation, the codon was changed to UAU instead of CAU. UAU codes for the enzyme, tyrosine, instead of histidine.
