The pressure must be halved.
The pressure must be quadrupled.
There is not enough information to decide.

Boyle's Law says volume and pressure are inversely proportional. In practical words that is this.
Volume goes up then pressure goes down or
Volume goes down then pressure goes up.
Or you can use p1v1 = p2v2
