$1.$ Pirelli believes that it can increase the per$-$unit revenue of the H$-$strand from $$300$K per strand to $$310$K per strand. This change would need to be reflected in which of following sections of the LP formulation:

a$.$ Constraints.

b$.$ Objective Function.

c$.$ Constraints and Objective Function.

d$.$ Decision Variables.

$2.$ If an optimization problem is deemed to be infeasible, adding another constraint to the LP would:

Group of answer choices

a$.$ Definitely make it feasible.

b$.$ Continue to keep it infeasible.

c$.$ Potentially make it feasible depending on the constraints that is being added.

d$.$ None of the options.

$3.$If the Pirelli company is able to improve the "pulling" process and increase production capacity from $200$ to $220$ fiber optic strands, we will find what change in the optimal solution compared to the original $($please resolve using Solver$)$:

a$.$ More of both strand A and strand H will be produced

b$.$ More of strand A will be produced but less of strand H

c$.$ More of strand H will be produced but less of strand A

d$.$ No change in the amount of either A or H
