What information must a professional contractor disclose in advertising?

A professional contractor is required to disclose specific information in their advertising to ensure transparency and build trust with potential clients. The correct choice emphasizes the necessity of including licensing information, business name, and address. This information serves several critical purposes: it lets potential customers verify the contractor's legitimacy and credentials, it helps to confirm that the contractor is appropriately licensed to conduct work in that jurisdiction, and it provides a means for prospective clients to reach out directly regarding services.

In the context of contracting, licensing information is particularly crucial, as it signifies compliance with local laws and standards that govern construction practices. Additionally, clearly stating the business name and physical address enhances accountability, as clients may need to follow up with the contractor or file complaints if necessary.

The other options do not meet the legal requirements or do not provide essential verification information. For instance, simply providing a phone number does not ensure the consumer can validate the contractor’s qualifications or locate them physically. Client testimonials and reviews, while valuable for marketing and building reputation, do not fulfill the regulatory obligations surrounding disclosure. Lastly, mentioning interior design styles does not relate to the fundamental business information that needs to be shared for compliance and does not contribute to the trustworthiness of the contractor's professional credentials.
