Question

A child swinging on a swing in sitting position stands up, then the time period of the swing will (A) increase (B) remain same (C) decrease (D) increase if the child is long and decrease if the child is short

The time period will decrease. When the child stands up, the centre of gravity is shifted upwards and so the length of swing decreases, hence from the expression of the time period which is given by T=2π √(l/g) , the time period will decrease.

increase if the child is long and decrease if the child is short

The time period will decrease. When the child stands up, the centre of gravity is shifted upwards and so the length of swing decreases, hence from the expression of the time period which is given by $T = 2 π \frac{l}{g}$ , the time period will decrease.
