Explanation:

Let’s break these down:

- Option 1: Documents

Forgery almost always deals with documents or writing. We're talking about making a false document or altering a real one with intent to deceive. That could be cheques, contracts, certificates—stuff that proves something or gives someone rights.

- Option 2: Property

Stealing or tampering with property isn’t forgery. That falls under theft or criminal misappropriation, not forgery.

- Option 3: Hurt

This is about physical injury or harm to a person. Nothing to do with forgery.

- Option 4: None of the above

This doesn’t fit, because one of the options actually is right.

So, yes, you nailed it. Forgery is all about documents and the authenticity of writing—nothing else.
