O A. The trivial equilibria (0, 0) is unstable. The equilibrium (20, 0) is locally unstable. The equilibrium (0, 17) is locally stable. The equilibrium at the non-trivial solution is locally stable.
OB. The trivial equilibria (0, 0) is stable. The equilibrium (20, 0) is locally unstable. The equilibrium (0, 17) is locally stable. The equilibrium at the non-trivial solution cannot be analyzed.
OC. The trivial equilibria (0, 0) is unstable. The equilibrium (20, 0) is locally unstable. The equilibrium (0, 17) is locally stable. The equilibrium at the non-trivial solution cannot be analyzed.
O D. The trivial equilibria (0, 0) is unstable. The equilibrium (20, 0) is locally stable. The equilibrium (0, 17) is unstable. The equilibrium at the non-trivial solution cannot be analyzed.
