  1. less than 4s

  2. more than 4s

  3. equal to 4s

  4. infinity

B Correct answer
Explanation

The time period of a simple pendulum is T = 2*pi*sqrt(L/g). At the North Pole, the effective gravity (g) is higher due to the Earth's rotation and shape. If the pendulum is moved to a location where g is lower (like the equator or mid-latitudes), the time period will increase.
