Correct answer: (D) i-c, ii-a, iii-b, iv-d

Explanation

Inkjet printers form the image by propelling tiny droplets of ink onto the paper.

An LCD screen is a flat panel display that uses the light-modulating properties of liquid crystals.

An LED screen is a flat panel display that uses an array of light-emitting diodes as its pixels.

A laser printer transfers electrically charged powdered toner onto paper and fuses it with heat.

This pairs inkjet with ink droplets, LCD with liquid crystals, LED with the diode array and laser with charged powder.

Most monitors sold as LED are really LCD panels lit by an LED backlight.
