Can you guys check my answer to this? i think its c but i'm not really sure. could you ? this is the question: the mitochondrial dna sequence that is shared by two species has a steady mutation rate. scientists determine the sequences of these two species to be as follows:

species a: caggccattatg
species b: ccagcctatagg

this dna sequence has a known mutation rate, which the scientists used to calculate that the species diverged from a common ancestor 80 million years ago. using this information, how much more time do you predict will pass before these species differ by a total of eight base pairs?
a.) 160 million years
b.) 32 million years
c.) 48 million years
d.) 240 million years
