In the substantive due process the court will look at the law and determine if it has or would have an unfair impact on a person's rights, meaning that all of the options are correct:

all people born in the united states have all the rights of citizens. laws will apply to everyone not just some people. the law will be applied fairly. the content and meaning of the law will be fair.

The content and meaning of the law will be fair.

Explanation:

Due Process of law, as guaranteed in the Fifth Amendment, is the law that states that no person shall be deprived of life, liberty, or property. It states that the law will remain fair and equal to both the civil and criminal in all legal matters.

Under the Fourteenth Amendment, Due Process of law is broken into two categories: Procedural Due Process and Substantive Due Process.

The Substantive due process deals with the subjects such as privacy and liberty of contract. The Substantive due process restricts the ability of the government to breach the constitutional liberties. It suggests that the substantive due process guarantees that the law will be fair in its content and meaning.

So, the last option is correct.
