B Correct answer
Explanation

The time period of a simple pendulum is T = 2π√(L/g), where g is acceleration due to gravity. Since g on the moon (1.62 m/s²) is about 1/6th of g on Earth (9.81 m/s²), the time period increases by a factor of √6 ≈ 2.45. Lower gravity means slower oscillation, hence longer period.
