When adventitious roots show swelling at regular intervals for food storage, it is called "moniliform root."

A moniliform root is characterized by a series of bead-like swellings or constrictions along the root, giving it a segmented appearance. Each segment represents a storage region where the plant stores nutrients and carbohydrates. The term "moniliform" is derived from the Latin word "monile," which means necklace, referring to the segmented structure of the root.

Moniliform roots are commonly found in certain plant families, such as the Euphorbiaceae (spurge family) and Fabaceae (legume family). One well-known example is the sweet pea plant (Lathyrus odoratus), which has moniliform roots used for food storage.

These specialized roots allow plants to store nutrients during favorable conditions and utilize them during periods of stress or dormancy. The segmented structure of moniliform roots maximizes the storage capacity, enabling the plant to have a reservoir of energy for survival and growth.

Hence, the correct answer is option 3.
