The Solver Sensitivity Report for some profit maximization problem with several constraints including x$1<=400$ and x$2<=1200$ looks like as below. What conclusion is not correct?

Final Reduced Objective Allowable Allowable

Cell Name Value Cost Coefficient Increase Decrease

$B$$16$ x$140080801$E$+3080$

$C$$16$ x$212001291291$E$+30129$

Final Shadow Constraint Allowable Allowable

Cell Name Value Price R$.$H$.$ Side Increase Decrease

$B$$21$ Resource$1$ availability $92000100001$E$+30800$

$B$$22$ Resource$2$ availability $2800030001$E$+30200$

Group of answer choices

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

If the coefficient of x$2$ stays within $-129$ to $129+1$E$+30,$ the optimal solution does not change at all.

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

The value of decision variable x$1$ will stay at $400$ unless the profit margin for x$1$ decreases by at least $$80.$
