Correct Answerसही उत्तर

C. ScannerC. स्कैनर

Explanationव्याख्या

The correct answer is Scanner.
According to the source, Scanner is an input device.
Speaker, Printer and Monitor are distractors in the original question.
The direct source-supported revision chain is therefore: Scanner — Input Device.
This question closely follows Q697, where Monitor is identified as an output device, so the two facts should be revised together: Scanner = Input; Monitor = Output.
The source provides no further explanation about the working process of a scanner, image capture, optical sensors, resolution or document scanning.
Therefore those details have not been added as source-derived information.
The question is straightforward but useful for classification-based exams, where familiar devices may be mixed across input and output categories.
Quick revision: Scanner = Input Device; Monitor = Output Device according to the source.
Therefore option (c), Scanner, is correct.

सही उत्तर Scanner है। स्रोत के अनुसार Scanner एक input device है। Speaker, Printer और Monitor distractors हैं। Direct source-supported association है: Scanner — Input Device। यह Q697 के तुरंत बाद आता है, जहां Monitor को output device बताया गया था। इसलिए दोनों facts साथ में revise करना useful है: Scanner = Input; Monitor = Output। Source scanner की working, optical sensors, resolution या document scanning process की details नहीं देती। इसलिए outside technical information add नहीं की गई है। Classification-based questions में input और output devices को mix करके पूछा जा सकता है। Quick revision: Scanner = Input Device; Monitor = Output Device। इसलिए विकल्प (c), Scanner, सही उत्तर है।
