The correct answer is: transversion mutation
The base pair mutations are most common type of mutations. These can be further categorised into two types
(a) Transitions, i.e. in which a purine base is replaced by another purine and pyrimidine is replaced by another pyrimidine.
(b) Transversion, i.e. those in which a purine (guanine) is replaced by a pyrimidine (cytosine) and vice-versa.
