The right answer is A. The author of the Chicago Times article on the opportunities awaiting settlers in the so-called "Unassigned Lands" was Elias Cornelius Boudinot (1835-1890), who published it in 1879. This colonel and attorney, who was the first one in popularizing the unofficial term "Unassigned Lands" in reference to lands in the central part of the Indian Territory (present-day Oklahoma) that had not been assigned to any of the Indian tribes that had been forced to move there, suggested that those lands could be inhabited by white settlers. This eventually occurred a few years later, in 1889.
