Which one is not metal

  • A.Sulphur
  • B.Sugar
  • C.Nitrogen
  • D.All of these

Answer: D

All of these - none of the three is a metal.

Sulphur and nitrogen are non-metallic elements, and sugar is an organic compound, not an element at all. A metal is lustrous, malleable and a good conductor; none of these fits.
