which other state is part of the same us climate region as north carolina?

california
louisiana
michigan
nevada

Both North Carolina and Louisiana are part of the same climate region, since both states have humid subtropical climates.

Explanation:

In North America, this type of climate is superimposed on the states of the southeastern United States. Northeastern Mexico also belongs to this area. It is approximately bounded by the Ohio River at Louisville, Kentucky, and Cincinnati where snow is common in winter. Further north is a humid continental type climate with cold winters. Finally, the Appalachians, which rise to more than 2,000 meters, disrupt the subtropical climate in Georgia and North Carolina. The southern boundary of the subtropical climate is close to the city of Miami and the south coast of Texas, where the tropical climate begins with warm temperatures all year round.
