Effective therapeutic communication skills require select one: a. verbal and nonverbal communication techniques b. correct use of complex medical terminology c. english-speaking patients or family members d. supervision by advanced life support personn

I believe the answer is A. verbal and nonverbal communication techniques
The verbal communication technique is used in order to dig deeper into the patient's subconcious mind.
And the non verbal communication technique is used to pick up small behavioral changes that may indicates a certain emotion from the patient (such as choking sound when telling a certain story)
