Match Printer types (List I) with their Characteristics (List II):
List I (Printer type) List II (Characteristic)
a. Inkjet i. Produces physical three-dimensional objects
b. Laser ii. Impact printer that uses pins striking ink ribbon
c. Dot Matrix iii. High-speed printing using toner powder
d. 3D Printer iv. Sprays liquid ink droplets onto paper
Codes:

Correct option is B

• Inkjet Printer → Sprays liquid ink droplets (List II: iv)
– Uses nozzles to eject tiny droplets of ink; commonly used for photo and color printing.
• Laser Printer → Uses toner powder with a laser mechanism (List II: iii)
– Works with electrophotographic process, enabling fast and high-quality printing.
• Dot Matrix Printer → Impact printing mechanism (List II: ii)
– Has pins that strike an ink-soaked ribbon forming dots → used where multipart forms are needed (banks, billing).
• 3D Printer → Produces physical 3D models (List II: i)
– Uses additive manufacturing to create solid objects layer-by-layer.
Thus, the correct matching is:
a-iv, b-iii, c-ii, d-i → Option (b)
