If the displayed system time and date is wrong, you can reset it using:

(A) Calendar
(B) Write
(C) Control Panel
(D) None of these

🧠 Explanation:

If the system time and date on a computer are incorrect, they can be reset using the Control Panel. In Windows, the Control Panel provides access to system settings, including Date and Time, where users can manually adjust or synchronize with an internet time server. The term “Control Panel” is a proper noun referring to this specific interface. Alternatives could include Settings in newer versions of Windows or System Preferences in macOS, but in traditional desktop terminology, Control Panel is the standard method. Correctly setting time and date is important for software functionality, scheduled tasks, and file timestamp accuracy, making this a key concept for PPSC-level computer literacy questions.
