Which of the following is a type of image scanner?
Answer: C
Correct answer: Flat-bed
A flat-bed scanner holds the document face down on a glass platen while a moving carriage carrying the light source and sensor traverses beneath it.
The arrangement suits bound books and fragile originals, since nothing is dragged through rollers. The other genuine type is the hand-held scanner, moved across the document by the user - and "hand-led" in the options is a misspelling of it, as "flat-held" is of the answer. Sheet-fed scanners are the third common form.
