Best answer
Correct answer is (c) Milk letdown and urine contraction

Easiest explanation: Release of the hormone oxytocin from the cow’s pituitary gland in the brain into the bloodstream, where it travels to the udder and causes several important processes to occur. Processes include milk letdown and urine contraction.
