In the figure above, a new beneficial allele, B, arises on a chromosome containing the ordered loci A, b, C, D, and E, depicted in the top panel

After reproduction, those chromosomes possessing the B allele increase in frequency. Over time, recombination breaks up the association of the B allele with the A, C, D, and E allele. The first pair of allele combinations to be broken up will be:
a. B and A.
b. B and C.
c. B and D.
d. B and E.
e. All will break up at an equal rate.
