Which of the following is key in making a positive first impression?

The key to making a positive first impression lies in nonverbal communication, particularly through smiling and maintaining eye contact. These gestures convey friendliness and openness, making the other person feel welcomed and valued. A genuine smile can create an immediate sense of warmth and approachability, which can set the tone for a positive interaction. Eye contact demonstrates confidence and engagement, allowing for a stronger connection between individuals. Effective first impressions are largely rooted in establishing trust and rapport quickly, which smiling and eye contact facilitate.

While options like gift-giving or attire can impact impressions, they do not carry the same weight as the immediacy of nonverbal cues. Being late, even with an explanation, generally creates a negative perception as it can signal a lack of respect for the other person's time.
