The sex of a person is determined by the individual's X chromosome to autosome ratio in Drosophila. One X chromosome and two sets of autosomes, at a ratio of 1:1, produce a female fly. This is due to the fact that in Drosophila, the development of a female requires the presence of two X chromosomes, whereas the formation of a male requires the presence of one X chromosome and one Y chromosome.

Option 2 is the correct answer.
