Which of the following is a good example of business etiquette in a social situation?

A) Don't look guests from other cultures in the eye
B) Only shake hands when someone else extends their hand first
C) Finishing a text message while introducing yourself to someone
D) Briefly describe your role in the company when you introduce yourself
E) A personal comment that includes mild flattery

Briefly describing your role in the company when introducing yourself is a good example of business etiquette in a social situation because it shows professionalism and gives the other person an idea of your position and responsibilities.

Other options are not good examples of business etiquette. Looking away while speaking to someone can be interpreted as disrespectful or uninterested, only shaking hands when someone else does it first can come across as hesitant or disinterested, finishing a text message while introducing yourself is plain disrespectful, and making personal comments including flattery can be seen as insincere or inappropriate.
