Important Note: For all questions requiring a Sensitivity Report please use Analytic Solver Platform's Standard LP/Quadratic Engine. Consider the following LP problem:
MAX: ​4X1​+2X2​
Subjectto: 2X1​+4X2​≤20
3X1​+5X2​≤15
X1​,X2​≥0​

Identify the different sets of basic variables that might be used to obtain a solution to the problem.
I. Unique. Only available solution.
II. Not unique. One altemative solution.
III. Not unique.
