Final answer:
Article 1 of the Texas Constitution with its various rights and protections is an example of the constitutional principle of limited government. Hence, the correct answer is option B.
Step-by-step explanation:
The rights and protections listed in Article 1 of the Texas Constitution, such as freedom and sovereignty of the state, a republican form of government, and equal rights among others, exemplify which constitutional principle? These are examples of constitutionalism, which includes limited government as a principle.
Limited government ensures that the powers of the government are constrained to protect individual liberties and prevent any governmental body from becoming too powerful. This aligns with the protection of civil rights and the establishment of a government with authority that is derived from and accountable to the people, as seen in both the U.S. Constitution's Bill of Rights and the principles articulated regarding the Texas Constitution.
