If a driver lives in one state, and is employed in another state, which state competition can he/she compete in?

Answer: D — It's the driver's choice

In this scenario, the choice that allows the driver to compete in the championship is determined by their own preference. Competitors generally have the flexibility to select which state competition to enter based on their personal circumstances and affiliations. This means that if a driver lives in one state but works in another, they can choose either the state of their residence or the state of their employment for competition. Such flexibility encourages participation and allows drivers to represent the state they feel most connected to, whether that be due to residency or professional ties. Other options present constraints that do not align with the typical rules of competition, as they suggest limited choices based on employment status or residence alone, which does not reflect the inclusivity typically encouraged in state-level competitions.
