Hint:

Answer 1

The Correct Option is B

The toner cartridge is often called the ‘heart’ of the image formation system in a printer, especially in laser printers. It contains the toner powder (a fine, dry mixture of plastic particles, carbon, and coloring agents) that forms the actual image on paper.
During printing, the toner cartridge transfers the toner to the paper through an electrostatic process, producing the desired text or images. Without the toner cartridge, printing would not be possible.
