The correct answer to this open question is the following,
In 1829, President Andrew Jackson offered to buy Texas from Mexico for $5 million. The Mexican government responded to President Jackson's offer to buy Texas with a negative. Mexican rulers did not agree.
The reaction of the Mexican government was to prohibit more American emigration to Texas. United States people and some Texans did not want to learn and assimilate the Mexican culture, did not want to convert into Catholicism, and never considered learning Spanish, the official language in México.
Texans did not consider themselves Americans, either Mexicans; they were Texans and were eager to form their own Republic.
I would say D as well. Animals need homes to live in... and they can't live in that area if the trees and plant life is always getting cut down.
