WILL FAN AND MEDAL! NEED HELP PLZ

You place a balloon in a closed chamber at standard temperature and pressure (STP). You halve the chamber pressure. What happens to the balloon?
It decreases to one-half of its original volume.

It stays the same volume.

It doubles in volume.

It expands to four times its original volume.
