The correct answer is:
increases
According to law of conservation of angular momentum,
\(I \omega=\text { constant }\)...(i)
where, \(I=\) moment of inertia and \(\omega=\) angular velocity.
When a ballet dancer suddenly folds her outstretched arms, then her moment of inertia decreases, hence from Eq. (i), we observe that her angular velocity will increases.
