Answer: Option B

The best method of milking is Full hand.
Milking is the act of removing milk from the mammary glands of cattle, water buffalo, humans, goats, sheep, and, more rarely, camels, horses and donkeys.
Hand milking is performed by massaging and pulling down on the teats of the udder, squirting the milk into a bucket.
The top of the teat is pinched shut between finger and thumb, trapping milk in the lower part, which is then squeezed by the other fingers, squirting the milk out through the hole in the tip of the teat.
