In which of the following primary root is short lived ?

In monocotyledonous plants, the primary root is short lived and is replaced by a large number of roots. These roots originate from the base of the stem and constitute the fibrous root system, as seen in the wheat plant. In Maize and Sugarcane, roots arise from the first few nodes of the stem and penetrate obliquely down into the soil and give support to the plant. They are called Stilt roots.
