To what value was the gauge pressure restored after the drop?

Explanation:
Gauge pressure is the pressure above atmospheric pressure. When a system experiences a temporary disturbance, the pressure can drop, but once the disturbance settles and the system returns to its original operating point, the gauge pressure recovers to that same baseline. In this scenario, after the transient drop the system returns to its prior condition, so the gauge pressure returns to 700 kPa—the original gauge level. The other values would imply a different steady-state baseline, but since the system settles back to the same operating point, the final gauge pressure is 700 kPa.
