After Considerable Effort,you Are Able to Collect and Analyze DNA

After considerable effort,you are able to collect and analyze DNA from the winged animal.You obtain the nucleotide sequence of the cytochrome c oxidase gene.When you compare this sequence to the sequence of the same gene in a bat,a rodent,a shrew,and a human,you find the following numbers of differences: winged animal-bat 11 differences
Winged animal-rodent 14 differences
Winged animal-shrew 15 differences
Winged animal-human 9 differences
Which hypothesis does this data support?

A) Of the mammals tested, the winged animal is probably most closely related to shrews.
B) Of the mammals tested, the winged animal is probably most closely related to humans.
C) Of the mammals tested, the winged animal is probably most closely related to rodents.
D) The winged animal is probably most closely related to bats, because bats also have wings.
