When Comparing the Sequences of a Homologous Gene in Four

When comparing the sequences of a homologous gene in four different species,one pair of species shows a 1% difference,whereas the other pair shows a 3% difference.Which pair diverged longer ago from their common ancestor and why?

A) The pair with a 1% difference;a smaller difference (1% instead of 3%) indicates that there has been less time to accumulate mutations.
B) The pair with a 1% difference;a smaller difference (1% instead of 3%) indicates that there has been more time to accumulate mutations.
C) The pair with a 3% difference;A larger difference (3% instead of 1%) indicates that there has been less time to accumulate mutations.
D) The pair with a 3% difference;A larger difference (3% instead of 1%) indicates that there has been more time to accumulate mutations.
