A)10 torr
B)50 torr
C)100 torr
D)200 torr
E)1000 torr

According to Boyle's law, for a given amount of gas at a constant temperature, the product of pressure and volume is constant. Therefore, if the volume is doubled, the pressure must be halved to maintain constant pressure-volume product. Thus, the new pressure will be 100/2 = 50 torr.
