Exchange of one nitrogenous base for another base is called as the substitution- The transition is the substitution of one type of base by other of its own type- Hence- purine is replaced with purine -adenine to guanine and vice versa- and pyrimidine is replaced with the pyrimidine -cytosine to thymine-uracil and vice versa- only- Substitution of purine base for a pyrimidine base or substitution of pyrimidine base for a purine base is called as transversion- Hence- adenine is replaced with thymine- uracil and guanine with cytosine- In the question- Transition replaces A -purine- to G -purine- and C -pyrimidine- to T -pyrimidine- while transversion replaces -xA0-C -pyrimidine- to G -purine- and T -pyrimidine- to A-purine- The correct answer is A-
