Final answer:
To seem engaged and sincere, maintain eye contact and nod while listening, as it shows active engagement and understanding. Avoid crossed arms and distractions, as these can convey disinterest or boredom. The correct answer is option C.
Step-by-step explanation:
If you want to seem engaged and sincere in your body language, the best option to choose would be to maintain eye contact and nod. Making direct eye contact shows that you are focused and interested in the conversation. Unlike avoiding eye contact, which can suggest a lack of self-confidence or friendliness, maintaining it signifies engagement. In addition, nodding while someone is speaking can indicate that you are actively listening and understanding what is being said. It's important to remember not to overdo it, as staring can be perceived as aggressive or uncomfortable.
Consider your body positioning as well; crossed arms can be interpreted as a defensive or closed-off stance, implying disinterest or displeasure. Similarly, being easily distracted or looking away frequently can convey a lack of engagement or boredom. Adjusting your facial expressions and being responsive to the other person's nonverbal cues are also critical components of effective communication.
