A. point mutation

point mutation is one in which a single base in the sequence is replaced by another base in the sequence. in this case, the nitrogenous base threonine is replaced by adenine. with a change in base, the coded amino acid can also be replaced, depending on whether this mutation is synonymous or non synonymous.
