<em>c. Knowing you will get to play miniature golf as soon as you collect 10 gold stars for your reward chart</em>
Explanation:
For operant conditioning, a fixed-ratio schedule is a reinforcement schedule where a reaction or response is only reinforced after a given number of responses.
Basically, the subject receives a fixed number of responses / reactions and the trainer then gives a reward.
An individual will get a reward, in this case play miniature golf, if he/she does a fixed number of responses.
