Explanation:

Transportation problems:
- In transportation problems, the nonsquare matrix is made square by adding a dummy row or a dummy column.
- This process is known as matrix balancing, where dummy rows or columns are added to make the matrix square.
- The addition of dummy rows or columns ensures that the total supply is equal to the total demand, making it easier to solve the transportation problem.

Correct statement:
- In transportation problems, the nonsquare matrix is made square by adding a dummy row or a dummy column.
Therefore, the statement "In transportation problems, the nonsquare matrix is made square by adding a dummy row or a dummy column" is correct, and not incorrect as mentioned in the question.
