B)0.30 atm
C)3.3 atm
D)4.8 atm
E)1.0 atm

According to Boyle's law, at constant temperature and moles, pressure and volume are inversely proportional. The initial pressure and volume can be represented as P1V1=P2V2. Plugging in the given values, we get (1.2 atm)(1.0 L) = P2(4.0 L). Solving for P2, we get P2 = 0.3 atm. Therefore, the final pressure of the gas is 0.3 atm.
