Answer:

Choice A, BCAD

Explanation:

Recombination frequency is a number that describes the proportion of recombinant offspring produced in a cross. In other words, it tells us how often does crossing over happen between the loci of two observed genes. The bigger the RF is, the larger is the distance between two genes. That means that genes B and D (RF 14%) are the most distant ones, and all the others are located inbetween them. You have to sketch the order of genes based on how far away they are from each other.
