The given figure shows log magnitude versus ω plots of a system for different values of gain. For this system

curve 3 shows poorest gain margin while curve 1 shows highest gain margin

curve 1 shows highest gain margin and curve 2 shows poorest gain margin

gain margins shown by the three curves are equal

curve 1 shows poorest gain margin and curve 3 shows highest gain margin
