In a transduction experiment, phage P1 is grown on a bacterial host of genotype A+ B+ C+ and the resulting lysate is used to infect a recipient strain of genotype A– B– C–. The genes are in an order such that B is in the middle, and the distance between A and B is greater than the distance between B and C. Based on this information, which of the following least genotype?
