Local variables can be members of the auto, static, or register storage categories. Global variables can be used throughout the entire program and are not considered local variables. Const variables are not modifiable and extern variables are used to access variables from other source files. Therefore, the best choice for the missing storage category would be register. Local variables can only belong to the auto, static, or register storage categories. Of these three, const and external are not storage categories, and global variables do not belong to the set of local variables. Therefore, the best choice is D, register.
