The correct answer is I, II, III, and IV.
All four statements describe legitimate ways that data can be collected about you:
- I: Websites do indeed store data that tracks how you use the site (e.g., pages visited, time spent).
- II: Websites store cookies in your browser for user convenience like saving login information and preferences.
- III: Many apps can collect geolocation data from your phone to provide location-based services or for tracking purposes.
- IV: Credit card companies record transaction data for purchases made with their cards.
Thus, all options are valid methods of data collection.
