The closely spaced isobars indicate a strong pressure gradient force, which means there is a large difference in pressure over a small distance. This typically leads to strong winds. However, the fact that the spacing of the isobars increases away from you suggests that the pressure gradient force is weakening as you move away from the center of the system, which means winds will decrease. Therefore, the best choice is C.
