Which deciduous tooth typically has one root and no defined cusps?

Explanation:
In primary teeth, incisors have simple crowns with no cusps and usually a single root, while canines show a defined cusp and molars have multiple roots with more complex crowns. Among the options, the deciduous upper lateral incisor fits the description of having one root and no defined cusps. The upper deciduous canine has a cusp on the crown (a pointed projection), and the lower first and second deciduous molars usually have multiple roots and cusps. So the upper lateral incisor best matches the criteria.
