In solving the NLP problem, Solver found a degenerate model. This means that:
A) Solver is cycling and redundant constraints must be removed
B) a global optimal solution was found
C) the objective function changed very slowly for the last few iterations
D) a local optimum was found

A degenerate model in NLP means that the solver is cycling and redundant constraints must be removed in order to obtain a non-degenerate model. This is because the solver is unable to find a feasible solution due to the extra constraints in the model, causing it to cycle repeatedly without making any progress towards a solution. Removing these constraints will simplify the problem and allow the solver to find a feasible solution more easily.
