Solution

The correct option is B False

Lustre:

  • Metals have the property to display lustre.
  • Lustrous is a property of metals due to which they have shiny surfaces due to the reflection of light from the surface.
  • The intensity of the lustre depends upon the amount of light reflected from the surface, which is generally related to the refractive index of the material.

As a notebook and an eraser are non-metal, therefore they do not have lustre.

  • Notebooks are made up of paper which is derived from wood pulp and contains Carbon, (C) a non-metal.
  • Erasers are polymers derived from Carbon as a major raw material that is also non-metal.

Exception: Certain forms of Carbon like graphite and diamond exhibit lustre.

Therefore, the given statement is False.
