- Ga (Gallium): Has a very high boiling point and low toxicity, making it suitable for high-temperature thermometers.
- B (Boron): Boron fibers are extremely strong and used in making bullet-proof vests.
- Si (Silicon): Silicones (silicon-based polymers) are water-repellent and used in water-repellent sprays.
The correct matching is: (A)-(III), (B)-(I), (C)-(IV), (D)-(II).
