DNA-RNA hybridization is a technique used to determine the relatedness among different species. during hybridization scientists combine a single strand of dna from two different species they heat these combined strands in small increments and observe the temperatures at which most of the strands in the sample separate scientists compare the differences in separation temperature indicates fever base pair similarities between each organisms the table shows data for six species which pair of species is the most closely related?

A. Species 4 and 5
B. Species 5 and 6
C. Species 2 and 4
D. Species 2 and 6
