What did it mean to say that the people's natural rights are "inalienable"?

A-The rights apply to natural-born citizens rather than to foreigners.

B-The rights are dependent upon the good will of the monarch.

C-The rights cannot be taken away from the people.

D-The rights are dependent upon the good behavior of the people.

They can't take away those rights. like whatever rights they were there couldn't be anything done to take it away so they had to respect the rights and not do anything about it.

C-The rights cannot be taken away from the people.

It means they cannot be ''alienated'' or they are natural rights. Natural rights are those not contingent upon the laws, customs, or beliefs of any particular culture or government, and therefore universal and inalienable (i. e., rights that cannot be repealed or restrained by human laws).
