Solution
The correct option is C alveoli
After delivery, lactation occurs within the mammary gland; lactation involves the secretion of milk by the luminal cells in the alveoli.
Contraction of the myoepithelial cells surrounding the alveoli will cause the milk to be ejected through the ducts and into the nipple for the nursing infant.
Most women produce more than enough milk for their baby (or babies).
Rarely, a woman has breasts that do not produce enough milk because of insufficient of alveoli. Hence, A non-lactating mammary gland cannot produce milk because of lack of alveoli.
