Answer:
Encouragement response
Step-by-step explanation:
In psychology, an encouragement response takes place when you help someone by offering positive words of support and approval. In other words, we infuse courage to another person to reach a goal.
In this example your client is worried that he will not be able to find a job, you say "I know you can do it", you are infusing him courage to believe he has the qualities needed for that job and are offering him support. Thus, this is an example of encouragement response.
