Consider the sensitivity report below. The objective function of the linear program is Min 4x1+ 5x2+6x3.

An increase in the right hand side of constraint 2 by one unit would:

Variable Cells
			Final	Reduced	Objective	Allowable	Allowable
		Name	Value	Cost	Coefficient	Increase	Decrease
		x1	0	1.5	4	1E+30	1.5
		x2	80	0	5	1	5
		x3	0	1	6	1E+30	1
Constraints
			Final	Shadow	Constraint	Allowable	Allowable
		Name	Value	Price	R.H. Side	Increase	Decrease
		cst 1 (sign <=)	80	0	85	1E+30	5
		cst 2 (sign >=)	320	0	280	40	1E+30
		cst 3 (sign >=)	320	1.25	320	20	40

Select one:

a. decrease the objective function value

b. have no impact on the objective function value

c. increase the objective function value
