Hi. Unfortunately you didn't show what your textbook does about motivation. This prevents your question from being answered, as it directly asks for your textbook to be analyzed.
However, I will try to help you by showing you how you can find the answer to this question.
As you can see, all answer options refer to motivation. In this case, to answer this question, you should look in your textbook for all the topics where it addresses motivation, either explaining it or associating it with events and situations. You should read all these topics and understand how their author introduces the subject of "motivation" to you. After that, you should read all the answer options and identify the one that presents information similar to what you read in your textbook. That will be your answer.
