To solve this problem, we need to use the concept of isentropic compression, which is a process that is both adiabatic (no heat transfer) and reversible (no entropy change).

1. First, we need to find the specific entropy (s1) and specific enthalpy (h1) of the steam at the initial state (200 kPa, saturated vapor). We can find these values from the steam tables.

2. Since the process is isentropic, the specific entropy at the final state (s2) is equal to the specific entropy at the initial state (s1).

3. With the final pressure (3.0 MPa) and s2, we can find the specific enthalpy at the final state (h2) from the steam tables.

4. The work done on the steam during the compression process (W) is equal to the change in specific enthalpy (h2 - h1).

5. Finally, we can compare the calculated work with the options given in the question to find the correct answer.

Please note that without the actual steam tables, I can't provide the numerical solution to this problem.
