Explanation:
Statement 1: A monitor of a computer requires electricity to work.
- This statement is true. Monitors are electronic devices that require a power source to function.
- Monitors are connected to a power outlet using an AC power cord, and they need a continuous supply of electricity to display images.
Statement 2: A monitor of a computer has an inbuilt battery for supplying power to work.
- This statement is false. Monitors do not have built-in batteries.
- Unlike laptops or mobile devices, monitors rely on a direct power source and do not have a battery to supply power.
- If the power supply to the monitor is interrupted, it will turn off.
Statement 3: Monitor is also called Visual Display Unit.
- This statement is true. A monitor is often referred to as a Visual Display Unit (VDU).
- It is an output device that displays visual information generated by the computer.
- The terms "monitor" and "VDU" are used interchangeably to describe the same device.
Conclusion:
- Statement 1 is true.
- Statement 2 is false.
- Statement 3 is true.
- Therefore, the correct answer is D: Statement 1 and 3 are true.
