Which of the following is the second step of the intuitive lowest-cost method?
a. allocate as many units as possible to that cell without exceeding the supply or demand. then cross out that row or column (or both) that is exhausted by this assignment.
b. repeat steps 2 and 3 until all units have been allocated.
c. find the cell with the lowest cost from the remaining (not crossed out) cells.
d. identify the cell with the lowest cost. break any ties for the lowest cost arbitrarily.

The very first step of the lowest cost method is to find the cell with the lowest cost in the entire matrix representing the cost of transportation along with supply and demand.

C. Find the cell with the lowest cost from the remaining (not crossed out) cells.

Explanation:

The second step in the lowest cost method is to allocate as many units as possible to that cell (having the lowest cost) without exceeding the supply or demand.

Then cross out the row or column (or both) that is exhausted by the assignment made. These two steps are further repeated until all the assignments are made and the total cost of transportation is calculated at the end.
