1. The graph represents option C.
2. What we have is an exponential decay function. From the graph, we see that the points are 1200, 710, 440, ... Option c says that it loses \frac{2}{5} every year. This means that the decay factor is 1 - \frac{2}{5} = \frac{3}{5} = 0.6. The common decay factor represented by the points on the graph is also almost 0.6. So the graph represents the description in option C.
