C)a double row without a driver.Correct
# Explanation
Parking in a **double row without a driver** is considered to seriously obstruct traffic because the vehicle blocks the passage of other vehicles and cannot be moved quickly. On the other hand, if a driver is present, the vehicle can be moved when the need is detected; and double-row parking with a driver is only an infraction if it exceeds two minutes, not an immediate serious obstruction.
