Solution

The correct option is C A is true but R is false

Milk is initially secreted into small sacs within the mammary gland called alveoli, from which it must be ejected for consumption. Prolactin is a hormone secreted by the pituitary gland that stimulates milk production and this is stored in the alveoli. During breastfeeding, oxytocin promotes the movement of milk from the alveoli and finally its ejection through the nipple.
