When performing the minimum ratio test in the Simplex method and a tie occurs for the leaving variable, what special case does this cause in the next iteration?

It causes the special case of degeneracy. A tie in the minimum ratio test means two or more basic variables can leave the basis, and one of them may become zero in the next iteration.

It causes the special case of degeneracy. A tie in the minimum ratio test means two or more basic variables have the same minimum ratio, so one basic variable may become zero in the next iteration.

A tie in the minimum ratio test can cause degeneracy in the next iteration. It means two or more basic variables reach zero at the same time, so one of the resulting basic variables may be zero.

When there is a tie in the minimum ratio test, more than one basic variable can leave the basis. This can result in a basic variable becoming zero, causing degeneracy in the next iteration.
