The correct answer is "3. Both increase"
In fact, the frequency of a vibrating string is given by
where L is the length of hte string, T the tension and
the linear mass density.
We can see that string is made shorter, L decreases, so the frequency f increases. And since the pitch has the same behaviour of the frequency, it increases as well.
