Solution
The simple (Donders A) reaction refers to a situation where there is only one stimulus and one response. In this case, the correct answer is c. When a bicyclist sees a stop sign he puts on his brakes to stop. This is because there is only one stimulus (the stop sign) and one response (putting on the brakes). The other options involve multiple stimuli and/or multiple possible responses, which would make them either choice reactions (Donders B) or discrimination reactions (Donders C).
