Correct answer: C — Hemispatial neglect (attentional)

Explanation lettering: C = shown as A · E = shown as B · B = shown as C · A = shown as E

Hemispatial neglect is a disorder of attention, not vision. The patient can see left-field stimuli when directed but fails to spontaneously attend to them. It is most common after right parietal strokes. A: He can see left field when directed. C: Cortical blindness would affect both fields. D/E: Neurological context makes these unlikely.
