Solution

The answer is C) Brachial artery.

Here's why:

The cubital fossa is the triangular area on the anterior view of the elbow of a human. The proximal portion of the cubital fossa would be closer to the shoulder. The brachial artery is the major blood vessel of the upper arm and is the continuation of the axillary artery. It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow. Therefore, a puncture in the proximal portion of the cubital fossa would most likely affect the brachial artery.
