$A$ pendulum clock is set to give correct time at sea level. This clock is moved to a hill station at an altitude of $2500 \ m$ above sea level. In order to keep correct time at the hill station,the length of the pendulum:

  • A
    Has to be reduced
  • B
    Has to be increased
  • C
    Needs no adjustment
  • D
    Needs no adjustment but its mass has to be increased
