The correct answer is A) difficulty securing land titles from the Mexican government, and land disputes.
The challenge that both Anglo and Spanish settlers faced in Texas was difficulty securing land titles from the Mexican government, and land disputes.
At that time, the government of México owned the Texas territory, Mexican officials had few interests in settling this region. It was a faraway land for the Mexican government located in central México. It wanted to send people to inhabit Texas but few people from central Mexico were interested. That is why Mexican authorities allowed Texans to settle in but imposed many things that upset Texans such as speaking Spanish as the official language of Texas or the practice of Catholicism.
