Explanation:

- Non-cognizable offences are typically considered less serious. The police don't have the authority to make an arrest without a warrant or start an investigation without prior approval from a magistrate.

- Option 1 - Public wrongs: These usually refer to crimes that affect society at large, like theft or assault, which are typically cognizable.

- Option 2 - Private wrongs: Non-cognizable offences often relate to disputes or wrongs where the victim is an individual, such as defamation or minor disputes.

- Option 3 - Both public and private wrongs: This is not accurate for non-cognizable offences since these primarily involve private disputes.

- Option 4 - None of the above: This is incorrect because non-cognizable offences do relate to one of the categories.
