Drosophila melanogaster and Drosophila simulans are fruit flies that are identical in appearance except for small differences in their genitalia. Hybrids can be produced, but they are sterile. On a basis of this information you can conclude that D. melanogaster and D. Simulans meet the criteria to be considered;
1. different biological species and different morphospecies
2 . different biological species but same morphospecies
3. same  biological species and different morphospecies
4 . same biological species and the same morphospecies

Tell your professor that geneticists should keep their noses out of taxonomy. Dobzhansky's "biological" species concept is worthless for most organisms (extinct, asexually-reproducing, or both) and has crapped up the education of all too many biologists. If the prof is a geneticist, I wouldn't tell him this until you have gotten your final grade, though.

Oh, and real biologists (not geneticists) call these "sibling species".
