Correct answer: E — Cords
The infraclavicular block targets the cords of the brachial plexus as they surround the axillary artery deep to pectoralis minor. This approach provides reliable blockade of all terminal branches including the musculocutaneous nerve (which may be missed with axillary approach). It is less likely to cause phrenic nerve palsy compared to interscalene block.
