Constant Pressure Process 1-2:
- During this process, the ideal gas undergoes a constant pressure change from state 1 to state 2.
- Using the ideal gas law (PV = nRT), we can determine the ratio of the final temperature T2 to the initial temperature T1.
- Given that T2 = 3T1/4, we can write P1V1/T1 = P2V2/T2.
- Since the pressure is constant, P1V1/T1 = P2V2/T2 simplifies to V2/V1 = T2/T1 = 3/4.

Constant Volume Process 2-3:
- In this process, the ideal gas undergoes a constant volume change from state 2 to state 3.
- Again using the ideal gas law, we can determine the ratio of the final temperature T3 to the initial temperature T1.
- Given that T3 = T1/2, we can write P2V2/T2 = P3V3/T3.
- Since the volume is constant, P2V2/T2 = P3V3/T3 simplifies to P2/P3 = T2/T3 = 3/2.

Final Volume to Initial Volume Ratio:
- Combining the ratios from the two processes, we have V2/V1 = 3/4 and P2/P3 = 3/2.
- Using the ideal gas law, P1V1/T1 = P2V2/T2 = P3V3/T3, we can determine the final volume to initial volume ratio.
- V3/V1 = (P1/P3) * (T3/T1) = (1/3) * (1/2) = 1/6.
- Therefore, the ratio of the final volume to the initial volume of the ideal gas is 1/6, which is equivalent to 0.75 or 75%. Hence, the correct answer is option B.
