Am I right?

Correct.

I don't know if your right. I have the same question on my test and I don't know the answer.

Yes, you are correct. The idea of "natural rights" refers to the belief that people are born with certain inherent rights that cannot be taken away. These rights are often considered to be universal and fundamental, such as the rights to life, liberty, and property. The concept of natural rights is closely associated with philosophers such as John Locke and the idea that these rights exist independent of any government or authority.
