B Correct answer
Explanation

The correct answer is 'increases' because when a person stands up on a swing, their center of mass moves higher, effectively shortening the length of the pendulum. For a simple pendulum, frequency is inversely proportional to the square root of its length (f = 1/2π × √(g/L)). Shorter pendulum length means higher frequency of oscillation.
