Which of the following is not a prezygotic isolating mechanism for two species found in the same geographical location?
A) The two species occupy different habitats.
B) The two species are active during different parts of the day.
C) The two species mate during different times of the year.
D) The two species have incompatible genitalia.
E) The two species can mate, but the offspring are sterile.
