We get pulse rate from

Vein
Artery
Skin
Nerve

The correct answer is B. Artery.

An artery is a blood vessel that carries oxygen-rich blood away from the heart to the body. The pulse is the wave of pressure that travels through the arteries as the heart beats. It can be felt at various points on the body, such as the wrist, neck, and ankle.

A vein is a blood vessel that carries deoxygenated blood from the body back to the heart. Veins are typically smaller than arteries and have thinner walls. They do not have the same pulse as arteries.

The skin is the largest organ in the body. It is made up of three layers: the epidermis, the dermis, and the hypodermis. The epidermis is the outermost layer of skin. It is made up of dead cells that are constantly being shed. The dermis is the middle layer of skin. It is made up of connective tissue, blood vessels, nerves, and hair follicles. The hypodermis is the innermost layer of skin. It is made up of fat cells.

A nerve is a bundle of fibers that carry messages from the brain and spinal cord to the rest of the body. Nerves do not have a pulse.
