Explanation:

Isothermal Process:
- In an isothermal process, the temperature of the gas remains constant throughout the process.
- Heat interaction (Q) is equal to work interaction (W) in an isothermal process.
- This is because the temperature remains constant, leading to the heat energy being completely converted into work done on the surroundings.

Non-flow Thermodynamic Process:
- In a non-flow thermodynamic process, there is no mass transfer across the system boundary.
- The process occurs within the system without any mass flow in or out.

Given Conditions:
- The question states that during the process (1-2) for a perfect gas, the heat interaction is equal to the work interaction (Q12 = W12).

Analysis:
- When Q12 = W12, it implies that all the heat supplied to the system is converted into work done during the process.
- This condition is specifically observed in an isothermal process where the temperature remains constant.

Conclusion:
- Therefore, the correct answer is option 'c) Isothermal,' as it is the only type of process where the heat interaction is equal to the work interaction, as mentioned in the question.
