Step-by-step explanation
Caesium is used in devising photoelectric cells. Boron fibres are used in making bullet-proof vest. Silicones being surrounded by non-polar alkyl groups are water repelling in nature. Gallium is less toxic and has a very high boiling point, so it is used in high temperature thermometers.
| Column I (Element) | Column II (Uses) | ||
| i | c | Photoelectric cell | |
| ii | a | High temperature thermometer | |
| iii | d | Bullet-proof vest | |
| iv | b | Water repellent sprays |
