In a federal system of government, legislative items constitutionally reserved for only the central government fall under the _________ list.

The legislative items that are constitutionally reserved for only the central government in a federal system of government fall under the "exclusive" list. This means that only the central or federal government has the authority to make laws and regulations on these specific topics. The exclusive list typically includes areas such as national security, foreign affairs, and currency. In contrast, concurrent and residual lists refer to areas where both the central and state governments can make laws, and the residual list refers to areas where the state government has the authority to make laws if the central government has not already done so.
