Which of the following is a right protected by the Constitution?

The right to free speech is a fundamental civil liberty protected by the First Amendment of the United States Constitution. This amendment guarantees individuals the freedom to express themselves without government interference or regulation. It is a cornerstone of American democracy and plays a crucial role in fostering open discussion, debate, and the exchange of ideas, which are vital components of a healthy and functioning society.

In contrast, the other options mentioned do not carry the same constitutional protection. The right to work, for instance, is not explicitly stated in the Constitution and may vary based on state laws and regulations. Similarly, while the right to a job is a desirable aspect of economic opportunity, it is not recognized as a constitutional right. Lastly, the right to own a car is also not protected by the Constitution; vehicle ownership is regulated by laws at various levels of government, and there is no constitutional guarantee that individuals have the right to own a vehicle. Thus, the right to free speech stands out as the clear choice with direct constitutional backing.
