Answer this question with respect to the CONSULTANT PROBLEM posted in Canvas $($Test $6$ Output document above$).$ Any proposed changes to the CONSULTANT PROBLEM pertain only to that problem. Do not carry forward changes made in one problem to another problem. Assume that Client D suddenly increases the number of required hours from $85$ to $105.$ In solving the CONSULTANT PROBLEM, which of the following statements becomes true?

The demand constraint for client D will have to be changed, but a new dummy supply node with capacity $20$ is needed.

Nothing about the formulation needs to be changed.

The demand constraint for client D will have to be changed, but no new dummy supply node is needed.

The problem is now infeasible.
