In Transduction, Bacterial Genes Become Packaged into a Viral Coat

In transduction, bacterial genes become packaged into a viral coat, are transferred to another bacterium by the virus, and become incorporated into the bacterial chromosome by crossing over. Bacterial genes can be mapped with the use of generalized transduction.
-In gene mapping experiments using generalized transduction, bacterial genes that are cotransduced are

A) far apart on the bacterial chromosome.
B) on different bacterial chromosomes.
C) close together on the bacterial chromosome.
D) on a plasmid
