Correct Answerसही उत्तर

D. MonitorD. मॉनिटर

Explanationव्याख्या

The correct answer is Monitor.
According to the source, a monitor is an output device.
Therefore it is the option that is NOT used for entering data into a computer.
Mouse, Keyboard and Scanner are presented as data-entry or input devices in the context of this question.
The direct source-supported association is: Monitor — Output Device — Not used to enter data.
This concept is reinforced in the following question where Scanner is specifically identified as an input device.
The source does not provide detailed definitions or working principles for Mouse, Keyboard or Scanner in this entry.
Therefore those details have not been added.
Students should pay attention to the negative word 'NOT'.
A reverse question may ask which of these is an output device; based on the source, Monitor would be correct.
Quick revision: Input
Data Entry — Mouse, Keyboard, Scanner; Output — Monitor.
Therefore option (d), Monitor, is correct.

सही उत्तर Monitor है। स्रोत के अनुसार Monitor एक output device है। इसलिए यह computer में data enter करने के लिए use नहीं किया जाता। Mouse, Keyboard और Scanner इस question के context में input/data-entry devices हैं। Direct source-supported association है: Monitor — Output Device — Data Entry के लिए नहीं। अगला question Scanner को specifically input device बताता है, जिससे यह distinction reinforce होता है। Source Mouse, Keyboard या Scanner की detailed working इस entry में नहीं बताती। इसलिए outside information add नहीं की गई है। Students question में 'NOT' शब्द पर विशेष ध्यान दें। Reverse question हो सकता है: इनमें से output device कौन-सा है? Source के अनुसार Monitor। Quick revision: Input/Data Entry = Mouse + Keyboard + Scanner; Output = Monitor। इसलिए विकल्प (d), Monitor, सही उत्तर है।
