Which of the following freedoms is included in the rights of all US citizens?

The freedom of speech is a fundamental right guaranteed to all U.S. citizens by the First Amendment of the Constitution. This amendment protects individuals' rights to express their opinions, ideas, and beliefs without government interference, which is essential for a democratic society.

The other rights listed, while important, are not explicitly outlined in the U.S. Constitution as fundamental freedoms. For example, while freedom to travel is generally accepted, it is not codified as a specific right. Similarly, freedom to own property and freedom to work may be protected under various laws and regulations, but they do not hold the same constitutional status as freedom of speech. Thus, the prominence of freedom of speech establishes it as a cornerstone of American democracy and a clear right afforded to all citizens.
