Which group among the following is insulator?
✓

Answer

  1. Paper, glass, cotton
Explanation:
Glass, paper, and cotton are good quality insulators. The rest options contain one or more conducting materials. Silver is the best conductor material available in nature. But it is costly, so it can’t be used in the electricity distribution system.
