Which of the following is an example of a common connection?

The example of a common connection that is most relevant involves shared relationships or experiences that can create rapport and trust. When you highlight that your brother-in-law has a friend who could benefit from your offering, it showcases a direct link between you and the potential buyer through a mutual acquaintance. This connection can enhance the credibility of your introduction or pitch, as it suggests that the potential buyer is already indirectly validated through a person they know.

In contrast, while the other options also represent connections in some way, they may lack the same level of direct social proof or relational depth. For instance, sharing a hometown or attending the same university can provide common ground, but without the endorsement of a mutual contact, these connections may not carry the same weight. Meeting a prospect at an industry event indicates that you share a professional context, but it doesn't inherently create a deeper trust relationship like a mutual acquaintance does. Therefore, option A stands out as a prime example of how personal connections can powerfully influence sales opportunities.
