In a linear programming graph, the best (optimal) solution always occurs at a point called what?

In a linear programming graph, the best optimal solution always occur at a point called:

Extreme Point.

Step-by-step explanation:

As we know that the optimal solution is the solution that is a feasible solution and satisfies the objective function.

The objective solution always exist at the corner point of the feasible region and the objective function is either a minimization or a maximization function and hence such a point will is a objective solution is called a extreme point.
