Answer:

The first pair of sequence.

This is because transitions are interchangeable of two ringed purines A to G or of one ringed pyrimidine C to T they therefore involves bases of similar shapes.

Transition mutations are generated at higher frequency than transformation which is interchangeable of purines for pyrimidine bases which involves exchange of one ring and two ring structures.
