It would be a. Because it keeps your browsing hidden

Yes, a.

The correct answer is c. In-Private (or Incognito) browsing allows the storage of some cookies and internet files so that webpages will still work correctly, but at the end of the in-private browsing session, this information is discarded.

To explain how I arrived at this answer, let's break down the options:

a. It keeps your browsing completely hidden from everyone: This is not true. In-Private browsing does not provide complete privacy. It only prevents your browsing history, cookies, and temporary internet files from being stored on your device. However, your internet service provider, the websites you visit, and other parties can still track and monitor your online activities.

b. It hides your IP address from the sites you visit: This is also not entirely accurate. In-Private browsing does not hide your IP address. Your IP address is still visible to the websites you visit, but the browsing session itself does not save any data related to your activities.

c. It allows the storage of some cookies and internet files so that webpages will still work correctly, but at the end of the in-private browsing session, this information is discarded: This is the correct answer. In-Private browsing allows limited storage of cookies and internet files necessary for proper website functionality during the session. However, once you close the In-Private browsing window, these temporary files and cookies are promptly deleted.

d. It prevents the end-user from registering their computer with the manufacturer: This option is unrelated to In-Private browsing. The ability to register a computer with the manufacturer is a separate feature or action that may or may not be available depending on the device and manufacturer's policies.
