In the simplex tableau, this is implied by a negative coefficient in the pivotal column. Before moving forward, the steps of determining the pivotal row are given below:

1. Take each positive coefficient in the pivotal column.

2. Divide each of these into the right-hand side constant for the corresponding row.

3. Identify the row that has the minimum ratio.

4. Pivotal row is the row that is identified in the previous step.

The correct answer is A.
