Answer»

The correct option is (a) Yellow-bodied, white-eyed FEMALES with brown-bodied, red-eyed males

For explanation I WOULD say: Morgan used DROSOPHILA as a genetic model to visualize the changes in the CHROMOSOMAL patterns and explain the observations of MENDEL. For this, he performed a dihybrid cross of yellow-bodied, white-eyed females with brown-bodied, red-eyed males.
