Sex in humans or animals is determined by the pair of chromosomes present in them.
In humans, it is the chromosomes X and Y that determine whether a person is male or female whereas in birds, the sex is determined by the pairs Z and W.
It can be a combination of either ZW, or ZZ. In certain cases these chromosomes are not limited to birds, but are used by some reptiles, fishes and amphibians too. But according to general characteristics here the choice (3) i.e. the bird, is the most relevant.
