The correct answer is: 1) Setting a password/PIN-protected lock screen

Explanation:

  • Physical Security: Prevents unauthorized access if the device is lost or stolen.
  • Foundation for Other Protections: Many security features (e.g., encryption, remote wipe) require a lock screen to be effective.
  • Simple but Critical: A strong PIN/password is the baseline for all other security measures.


Option Analysis 
 2) Turning off mobile data → Limits functionality but doesn’t protect against physical theft or malware.
 3) Using only free Wi-Fi networks → Increases risk (public Wi-Fi is often unsecured).
 4) Installing more apps → Irrelevant (and risky if apps are untrusted).
