If the universe is bounded, it means that it has a finite amount of space. In this case, the gravitational forces present in the universe will eventually cause it to stop expanding and to start contracting. This contraction will continue until all matter in the universe is compressed into a single point, a scenario known as the Big Crunch. Therefore, option B is the correct answer.
