Option C is correct, because, from the big bang theory clip, we know that Sheldon was used to changing Penney's behavior as positive reinforcement.
<h3>What Does Positive Reinforcement Mean?</h3>
Positive reinforcement: Sheldon rewarded Penny with chocolates whenever she displayed appropriate behavior, such as not occupying his seat, remaining silent, or speaking in a lower register. This makes Penny's likelihood of repeating these positive behaviors higher.
When a behavior is followed by the introduction of a pleasing or desirable stimulus, this is known as positive reinforcement. The desirable stimulus reinforces the behavior, increasing the likelihood that it will happen again.
Hence option C is correct.
