$A$ liquid is kept in a closed vessel. If a glass plate (negligible mass) with a small hole is kept on top of the liquid surface,then the vapour pressure of the liquid in the vessel is

  • A
    More than what would be if the glass plate were removed
  • B
    Same as what would be if the glass plate were removed
  • C
    Less than what would be if the glass plate were removed
  • D
