In solving the NLP problem, Solver produced a message "Solver found a solution. All constraints and optimality conditions are satisfied." This means that Solver found:
A) a local optimal solution
B) a global optimal solution
C) the objective function changed very slowly for the last few iterations
D) a degenerate model

Solver's message indicates that it found a solution that satisfies all constraints and optimality conditions, but it does not specify whether the solution is local or global. In non-linear programming (NLP), solvers often find local optima because they use gradient-based methods or other heuristics that do not guarantee global optimality.
