Solution

The correct option is C Linkage
The tendency for alleles of different genes to be passed together from one generation to the next is called as linkage. Only genes situated on the same chromosome can show linkage. In Drosophila the genes A and B did not show independent assortment as they were linked. Thus the correct answer is option A.
