Consider the following linear programming model: Max 2X+4Y + 6Z Subject to Z0 X+Y+Z20 X, Y, ZZO Reference: LP Model 1 Suppose that when the RHS of Constraint 1 increases by 3 units within the allowable A. the solution did not change. OB. the reduced cost must be 2. OC. the shadow price must be 2 O D. the constraint is no longer binding. OE. None of the above
