Two genes, designated A and B, are located 10 mu from each other. A third gene, designated C, is located 15 mu from B and 5 mu from A. A parental generation consisting of AAbbCC and aaBBcc individuals were crossed to each other. The F1 heterozygotes were then test crossed to aabbcc. Assuming nor double crossovers occur in this region, what percentage of offspring is expected with the following genotypes?

A. AaBbCc
B. aaBbCc
C. Aabbcc
