Show answer & explanation
Correct answer: A
Concept
Laser printers use electrophotography: a photoconductor drum carries an electrostatic image, and dry toner adheres to the charged image before transfer to paper.
Inkjet printers instead eject liquid ink through nozzles; their print-head carriage commonly moves from side to side.
Application
Statement A describes the rotating photoconductor drum stage, so it belongs to the laser-printing process.
Statement B names powdered toner, the dry imaging material used in laser printing.
Statement C describes droplet ejection through nozzles, an inkjet mechanism.
Statement D describes the moving print-head carriage used in typical inkjet printers.
Cross-check and contrast
A and B only keeps the two laser-printing mechanisms together.
C and D only groups the two inkjet mechanisms.
A and C only mixes one laser-printing mechanism with one inkjet mechanism.
B and D only also mixes one laser-printing mechanism with one inkjet mechanism.
Therefore, the applicable statements are A and B only.
