Final answer:
Crossing arms. Crossing arms can give the impression of being closed off or defensive, which can hinder effective communication with a client. The correct answer is C.
Step-by-step explanation:
The correct answer is C. Crossing arms. Positive body language to use when connecting with a client includes making eye contact, smiling, and using open gestures. Making eye contact shows that you are engaged and attentive, while a smile conveys friendliness and openness.
Using open gestures, such as relaxed arms and open palms, indicates approachability and receptiveness. However, crossing arms can give the impression of being closed off or defensive, which can hinder effective communication with a client.
