The Solver Sensitivity Report for some profit maximization problem with several constraints including x1<=400 and x2<=1200 looks like as below.

		Final	Reduced	Objective	Allowable	Allowable
Cell	Name	Value	Cost	Coefficient	Increase	Decrease
$B$16	x1	400	80	80	1E+30	80
$C$16	x2	1200	129	129	1E+30	129
		Final	Shadow	Constraint	Allowable	Allowable
Cell	Name	Value	Price	R.H. Side	Increase	Decrease
$B$21	Resource1 availability	9200	0	10000	1E+30	800
$B$22	Resource2 availability	2800	0	3000	1E+30	200

What conclusion is not correct?

Group of answer choices

For this problem, increasing the availability of resources by 1 unit will not impact the optimal value.

The value of decision variable x1 will stay at 400 unless the profit margin for x1 decreases by at least $80.

If the coefficient of x2 stays within -129 to 129+1E+30, the optimal solution does not change at all.

For this problem, decreasing the availability of resources can impact the optimal value.
