Final answer:
The correct synonym for 'refuse' in the context of client engagement is 'Decline'. Music therapy, which is the broader topic of the question, is a health-focused intervention that uses music exercises to achieve various therapeutic goals.
Step-by-step explanation:
The question asks for the synonym of the word in the context of clients' responses to music therapy. The correct answer is B) Decline. This is because 'decline' is a synonym for 'refuse' and fits the context of clients choosing not to engage in music therapy. Unlike 'decline', 'accept' is an antonym of 'refuse' and therefore does not suit the context provided. Both 'reject' and 'deny' could also be considered correct in a broad sense, as they are similar to 'refuse', but 'decline' is more appropriate for the formal or polite context implied in the question.
Music therapy is a therapeutic approach that uses music interventions to accomplish individualized goals. As a health-focused therapy, it connects deeply with clients because music is a universal language that can influence emotions, behaviors, and cognition.
