Water for supplying a building is stored in a system formed by two identical reservoirs, in the shape of a rectangular block, connected to each other by a pipe equal to the inlet pipe. Water enters the system through the inlet pipe in Reservoir 1 at a constant flow rate and, upon reaching the level of the connecting pipe, begins to supply Reservoir 2. Assume that initially both reservoirs are empty. Which of the graphs best describes the height $h$ of the water level in Reservoir 1, as a function of the volume $V$ of water in the system?
