```							A and B are the correct answer....Since x3+ax2-c=0 has three real roots … It implies that it has a maxima and minima as well at x=(-2a/3) and x=0 respectively...On putting x=(-2a/3) and x=0 in equation f(x)=x3+ax2-c we get (4a3-27c)/27 and (-c) respectively.Hence for just one solution of f(x)=k, we get k>(4a3-27c)/27 and kApprove my answer if you like it....
