Final answer:
To track anonymous visitors to a website, B. Web Page Activity Report is the appropriate choice as it details interactions with site pages by all visitors, including unidentified ones.
Step-by-step explanation:
If you want to see anonymous visitors to your websites, you would run the B. Web Page Activity Report. This report provides details on all visitors' interactions with your website's pages, including those who have not identified themselves through form submission or other identification methods. It usually includes information such as page views, time spent on page, and referrer information. This kind of report is typically found in web analytics and marketing automation platforms, helping to understand the behavior of all visitors, not just the ones who have converted into leads.
