The correct answer is D. The subscapular artery is the largest and most distal branch of the axillary artery, and forms an anastomosis with branches of the subclavian artery. These anastomoses can permit blood to flow from the subclavian to the axillary systems, or vice versa.
The vessels in the other answer choices do not anastomose with the distal axillary system.
