Explanation:

- Option 1: It is purely a personal right created by an order of criminal Court

- Section 125 of the Cr. P.C. provides a personal right to maintenance. It arises through a court order under the criminal procedural framework.

- Option 2: There is no charge created on property by the order for maintenance

- Maintenance orders under Section 125 do not impose a legal charge on any property. They mandate periodic payments by the person obligated to provide maintenance.

- Option 3: The maintenance cannot be held to the alienable property

- Since no property charge is created, maintenance cannot be attached or directly linked to alienable property. This implies that the maintenance order is not secured by any property or asset.

- Option 4: All of them

- This implies that the statements made in options 1, 2, and 3 are all correct descriptions of the nature of maintenance under Section 125 Cr. P.C.

- Correct Answer: Option 4 - all of them
