The process shown in the T-V diagram is a vertical line, which indicates that the volume remains constant during the process. Since the process is vertical, there is no change in temperature, and thus the process must be isothermal. Furthermore, since the process is moving to the left on the diagram, the gas is being compressed. Therefore, the best choice is B: isothermal compression.
