Physics Help - Identifying what the graph represents

ImageUploadedByStudent Room1414957041.100833.jpg

Do you guys know which line represents the bulb and which represents a high-resistance fixed resistor? And what a low resistance fixed resistor might look like in a graph?

I've been trying to solve this and. I think A might represent the bulb since the bulb slowly builds up in light intensity but then again that could be B since it shows a steady build up. But a high fixed resistor is well, fixed so it's representation should look like a steady build-up, right?
