Explanation:

- Section 27 of the Evidence Act deals with the admissibility of certain aspects of information provided by an accused person in custody. It specifically relates to how this information leads to the discovery of a fact.

- Option 1 - The object found: The discovery of a physical object linked to a crime can be considered under this section.

- Option 2 - The place from where it is produced: The location where the object is found also plays a crucial role as it provides context and validation to the discovery process.

- Option 3 - Both (a) & (b): Section 27 encompasses both the discovery of the object and the details about the place from which it was recovered.

- Option 4 - Neither (a) nor (b): This is incorrect as both the object and the location are relevant under this law.
