Your light is green. A pedestrian using a white cane starts across the street in front of you at an unmarked crosswalk. What must you do?

Why

New York has a special right-of-way rule for blind pedestrians. Someone crossing with a guide dog or with a white or metal cane gets the right-of-way at any crosswalk, marked or unmarked, and you must yield even when the traffic signal or the normal right-of-way rules favor you. That is exactly why the green light in the second option does not settle it. The third option fails because the rule covers unmarked crosswalks too, and the manual's general pedestrian tips also tell you to yield at every crosswalk, painted or not. A blind pedestrian may not know you are there, so the duty sits entirely with the driver. When a white cane or a guide dog enters the crosswalk, your green light stops counting.
