Answer:
A) Signaling quality.
Explanation:
People perceive lawyers who dress poorly, or in cheap clothes, as people who do not make a lot of money with their potentially lucrative profession. The objective validity of this perception is fallacious, but it still has real life consquences that legal professionals should avoid.
By simply dressing in expensive clothes, a lawyer signals that he or she is a quality lawyer because buying expensive clothes require large sums of money that can be earned through a quality work in the legal profession. (for example, winning difficult cases can be very profitable).
