B Correct answer
Explanation

Android's security model prevents apps from changing network type (2G/3G/4G) programmatically without root access. The MODIFY_PHONE_STATE permission is only available to system apps or rooted devices. This restriction protects users from apps forcing them onto slower networks or bypassing user preferences.
