This question was addressed to me by my school principal while I was bunking the class.

The origin of the question is Inheritance Principles topic in chapter Principles of Inheritance and Variation of Biology – Class 12

Answer 1

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.
