Is a pronoun, no is an adjective, and a pronoun equals an adjective+pronoun.

So grammatically, no.

You can't use nouns directly, you should use them.

nobody

Of+ noun

Why did the previous one use yours?

Last one to use yours?

-Yours.

Is a pronoun, equal to

Adjective+noun, so

business

about

Yours = yours

business

As I said before, none can't be directly used with nouns, so it can't be said.

nobody

your

Business,

Instead, you should use the

nobody

about

your

business
