This female has two sex chromosomes, ZW, and the sex of her offspring can be determined.
A) Bird
B) Fruit Fly
C) Human
D) Turtle
E) Weevil

I understand that the ZW sex determination system is used for birds, fish, and some insects, but I cannot find specifically in which animal the sex can be determined between the potential answers birds, fruit flies, and weevils. If someone could offer some insight I'd really appreciate it.
