A father of a teenaged boy who has been truant says to the social worker "I am sick and tired of this. This boy is going to have to grow up and learn that the world does not owe him any thing. Nothing is going to be given to him." The social worker responds by saying: "You sound disappointed and frustrated as if your son has not learned some important life lessons." The social worker's response would be an example of:
a. Checking out perceptions
b. Clarifying unfamiliar terms
c. Eliciting specific feelings
d. Exploring the basis of conclusions
