Sensitivity analysis is concerned with how certain changes affect a. the feasible solution. b. the degenerative solution. c. the optimal solution. d. the unconstrained solution.

The answer here is letter C. The optimal solution. The optimal solution is the one that affects how certain things changes with sensitivity analysis. The optimal solution is a feasibility solution where the objective function of it is to reach the minimum and maximum value.

The answer to that would be magnesium

Variables,control,conclusion and finally scientific theory
