One of the characteristics of a chemical system in equilibrium is that the concentrations of the species involved (given by the curved lines) are constant and their values don't change once the equilibrium is reached. This means that, in the graph, the time from which the system is in equilibrium is approximately C, since the concentrations then become constant (a flat horizontal line).
Paying close attention, it is probably a little more to the right than C, but the idea is that equilibrium is established once the concentrations don't change.
