Answer:
D). Protestants.
Explanation:
The people who immigrated to Texas from different continents belonged to three main religious groups i.e. 'Christianity, Islam, and Judaism.' The majority of them were Catholic Christians who migrated to Texas from Europe. Even the ones who were protestants before migrating to Texas converted to Catholicism as then only they could be granted citizenship of Mexico. Therefore, the texas immigrant population included Catholic Christians, Muslims, and Jews as the Protestant population was already very less and that too got their faith converted. Hence, option D is the correct answer.
