The correct answer is option 'D', which means that all of the given options are established by the Civil Code of 1804, also known as the Napoleonic Code.

The Napoleonic Code was a comprehensive civil code enacted in 1804 under the leadership of Napoleon Bonaparte in France. It aimed to provide a uniform set of laws that would apply to all citizens of France, replacing the complex and inconsistent legal systems that existed before.

Equality before the law:
The Napoleonic Code established the principle of equality before the law. This means that all individuals, regardless of their social status, wealth, or birth, are equal in the eyes of the law. It ensured that everyone had the same rights and obligations and that justice would be applied equally to all citizens.

Secured the right to property:
Another important aspect of the Napoleonic Code was the recognition and protection of the right to property. It provided individuals with the legal right to own, use, and dispose of their property as they saw fit, within the limits of the law. This helped to promote economic stability and individual freedom.

Did away with all the privileges based on birth:
The Napoleonic Code also sought to eliminate the privileges and inequalities that were based on birth or social status. It abolished feudalism and the remnants of medieval laws that gave special privileges to the nobility and clergy. Instead, it established a meritocratic system where individuals were judged based on their abilities and achievements rather than their family background.

The Napoleonic Code was a significant legal reform that had a lasting impact not only in France but also in many other countries. It influenced the development of civil law systems in Europe, Latin America, and other parts of the world. Its principles of equality before the law, protection of property rights, and elimination of privileges based on birth continue to be fundamental principles of modern legal systems.
