Explanation:

- Mesne profit refers to the compensation that a person in wrongful possession of property pays to the rightful owner for the loss of income during their period of possession.

- It is important that there is a limit to the interest imposed on mesne profit to ensure fairness.

- Option 1: 10% per annum is relatively high and usually not standard for mesne profit interest rates.

- Option 2: 6% per annum sounds reasonable and aligns with common practices or statutory guidance.

- Option 3: 4% per annum is lower and might not fully compensate the loss incurred by the rightful owner.

- Option 4: 1% per annum is very low and is unlikely to serve as sufficient compensation.

Option 2: 6% per annum
