Solution
The correct option is A Decreases
When the girl is standing the mass is distributed across her height. when girl sits, the entire mass is at larger distance from hinge of swing, as the moment of inertia increases, the angular frequency will decrease to keep the angular momentum constant. Hence, correct answer is option B.
