Which of the following is NOT a criterion for an appropriate business gift?

In the context of selecting appropriate business gifts, the most critical criterion is the degree to which the gift is viewed as professional rather than personal. A gift that is too personal could be perceived as inappropriate or even create discomfort, as it might blur the lines between professional and personal relationships.

On the other hand, gifts for past favors help express gratitude, which is a positive and appropriate motivation behind gift-giving in a business setting. Giving gifts to everyone in similar circumstances promotes equality and fairness, thus maintaining professional integrity. Furthermore, ensuring that gifts are not extravagant reinforces the notion of professionalism and avoids any implication that one is attempting to influence decisions or create obligations.

Therefore, the idea that a gift should be personal does not align with the etiquette of business gifting, making this the correct choice.
