A website with the “.com” domain extension typically represents a commercial website. Therefore, the answer is D. Commercial website.

The .com domain is the most widely recognized and used top-level domain (TLD) on the internet. Originally, the .com domain extension was intended for use by commercial organizations. These are businesses and companies aiming to generate revenue through online activities, sales, or services.

While initially designed for commercial entities, the .com extension is now used broadly. Many different types of websites utilize .com, including blogs, personal sites, and organizations that may not be strictly commercial.

Understanding that .com generally indicates a commercial presence helps internet users quickly identify the purpose of a site. However, it’s important to evaluate each website individually to determine its credibility and intent, rather than relying solely on the domain extension. While “.com” often represents commercial, it’s also important to use critical thinking when evaluating websites.
