Explanation:

- Statement: A purchased a stamped paper in the name of a person whose name he intended to forge.

- Option 1: Attempt of cheating – Cheating involves deceiving someone to cause harm or wrongful gain, which hasn’t happened just by buying stamped paper.

- Option 2: Attempt of criminal misappropriation – Misappropriation means wrongfully using someone else’s property. Buying stamped paper doesn’t count as this.

- Option 3: Attempt of forgery – Forgery involves making a false document. Only buying a stamped paper is not an act of forgery; intention is there but no act done yet.

- Option 4: No offence – Just purchasing stamped paper with intent to forge, without doing any act towards making a false document, is not an offence under law.
