Consider the primal problem:

Which of the following is correct?

Correct option is A

We are tasked with analyzing the primal and dual linear programming problems and identifying the nature of the variables in the dual problem.
Step 1: Given Primal Problem
The primal problem is:


Additional Knowledge:
· The relationship between primal and dual problems helps verify the correctness of solutions using the Weak Duality Theorem or Strong Duality Theorem.
· Dual problems are widely used in economic and business optimization scenarios.
