What is the full form of IDC in the context of interior design?

The term IDC stands for "Interior Designers of Canada," which is a professional association representing the interests of interior designers across Canada. This organization plays a crucial role in promoting the value of interior design, providing professional development opportunities, and advocating for industry standards. By establishing credentials and fostering a professional community, IDC supports both emerging and established designers in enhancing their skills and advancing their careers.

The other options, while they include terms related to design, do not accurately represent the organization denoted by IDC in this context. The International Design Council is a more global entity and does not focus exclusively on interior design. The Interior Development Council and the Interior Design Community, although plausible, do not exist as recognized national organizations for interior designers in Canada. Thus, the choice of "Interior Designers of Canada" is the correct association reflecting what IDC symbolizes in the realm of interior design.
