D. All of the above. Depending on how much current is being drawn, the charge will last longer.
1A * 200h = 200Ah
10A * 20h = 200Ah
200A* 1h = 200Ah
Please note that this would likely not be true in real life since some of the energy will be turned into heat as it is conductedd thrugh the wires etc. Especially for a large load of 200A
