Answer:
B). Chronemics.
Step-by-step explanation:
Joaquin's confusion regarding the American pace of life exemplifies the 'chronemics' aspect of nonverbal behavior as it is based on his time perceptions. Chronemics exemplify a subcategory of 'non-verbal communication' and is usually referred to as the study of communicative function/role of time. It involves the correlative theories and observations relating to the humans' use of time like how one observes and perceives time or organizes it. Thus, Joaquin's confusion is affiliated with his reaction to the use of time frames by the Americans which plays a greater part to play in interactions and non-verbal behavior. Therefore, option B is the correct answer.
