C.
Explanation: The Oregon Treaty (1846) and the Mexican Cession (Treaty of Guadalupe Hidalgo, 1848) added vast areas in the West, increasing U.S. territory by roughly one-third. (The final adjustments to the southern border came later with the 1853 Gadsden Purchase, so A and B are incorrect; the population did not nearly double, so D is incorrect.)
