Correct answer: B — The junction of the medial one-third and middle one-third of the clavicle

The subclavian vein crosses the first rib at approximately the junction of the medial and middle thirds of the clavicle. The needle is typically inserted 1-2 cm below the clavicle at this point and directed towards the sternal notch. The vein lies anterior and inferior to the subclavian artery (separated by scalenus anterior).
