Which gestation range applies to gerbils?

Explanation:
Gerbil gestation runs longer than that of many other common lab rodents, lasting about a month. Because fetal development takes longer, parturition is expected roughly four weeks after mating. Shorter ranges correspond to species with faster development, like mice or rats, and a very short period isn’t compatible with mammalian pregnancy. So the option that reflects a roughly one-month gestation best fits gerbils.
