Which of the following is an example of active online data collection?

Active online data collection involves directly engaging with users to gather information. When users complete an online survey, they are providing information willingly and actively, often in response to specific questions tailored to gather insights. This method ensures that the data collected is intentional and often more detailed, reflecting the users' opinions, preferences, or experiences.

In contrast, the other methods listed involve passive collection of data without direct user engagement. For instance, collecting IP addresses, tracking user activity with cookies, and analyzing geographic locations all occur without users actively providing information or explicitly consenting to share that information at the point of collection. Instead, these methods monitor user behavior or demographics based on how the users interact with a website or service. Thus, the correct answer exemplifies the active nature of data collection through voluntary user participation.
