It is the artery that runs from the Aorta behind the collar bone. It supplies blood to the arms.
The left subclavian artery doesn't feed the carotid (neck pulse) so your answer would be the wrist.
Subclavian artey becomes axillary artery. Axillary artery becomes brachial artery. Brachial artery divides into radial and ulnar branches. You palpate radial artery at distal end of radius bone. So you feel a pulse betwwen radius and your fingers. So it is better felt than ulnar artery.
The superior or the upper extremity is served by the subclavian artery and vein. Subclavian means below the clavicle bone.
The blood vessel that has a pulse is an artery. Veins do not have enough blood pressure to register a pulse.
You have the axillary artery which supply the upper limb. It is continuation of subclavian artery and continue as a brachial artery.

The radial pulse is checked for vital signs.

The temporal artery.
A pulse can be felt where an artery crosses a bone. The main areas where the strongest pulse may be felt are the carotid artery in the neck, the brachial artery in the crook of the arm and the radial artery in the inner wrist.
The brachiocephalic artery is the first major branch off of the aortic arch, it gives rise to the right internal carotid artery and the right subclavian artery. The brachiocephalic artery is also sometimes called the brachiocephalic trunk, and may also be called the innominate artery.
Left ventricle pumps blood through the aorta, which then goes through the brachiocephalic trunk, and then through the subclavian artery and then into your axillary artery Sierra Q
