Is the answer A or B because C and D won't give me the rate constant?




From the graph it is clear that the reaction follows first order kinetics ($\ce{[X] = [X\_0] e^{-kt}}$) where $ [X\_0]$ is initial concentration. Taking $ln$ on both sides we get 
$\ce{ln[X] = ln[X\_0] +(-kt)}$ 
So if you plot a graph between $ln[X]$ and $t$ then you have the magnitude of slope as k ie the equilibrium constant. 
So correct answer is A.
