Explanation:

Let’s break it down:

- Option 1: Certificates issued by a government officer—Section 79 does talk about certificates and other public documents. But it’s not just about certificates.

- Option 2: Certified copies issued by a government officer—Yes, this is spot on. Section 79 mainly concerns certified copies of public documents, typically issued by government officers.

- Option 3: Other documents duly certified to be genuine by a government officer—This fits too, since the law isn’t limited to just certificates or copies; it’s about any public document certified as genuine.

- Option 4: All of the above—So now you see, the section covers all of these. It’s about ensuring trust in official, certified documents and copies.

Option 4 is correct: all of the above.
