Question

which was one of the causes of the mexican war? a. the dispute over the border between california and the oregon territory b. the dispute over the border between new mexico and mexico c. the dispute over the border between texas and mexico d. the dispute over the border between texas and louisiana

Explanation:

The Mexican - American War (1846 - 1848) had a major cause related to the border dispute between Texas (after its annexation by the US) and Mexico. Mexico did not recognize the Rio Grande as the southern border of Texas (claiming the Nueces River as the border), while the US supported Texas's claim of the Rio Grande. Option A is about California and Oregon (not related to the Mexican War's main border dispute). Option B is about New Mexico, but the key dispute was over Texas - Mexico. Option D is about Texas and Louisiana, which is not relevant to the Mexican War. So the correct option is C.

Answer:

C. the dispute over the border between Texas and Mexico
