Rohan's property was wrongfully advertised for sale for recovery of government revenue due from Mohan. In order to save his property, Rohan paid the government dues. In this case, Rohan is entitled to recover the number of dues paid by Mohan on the basis of:
Government contract
Valid contract
Quasi-contract
Both B and C
In this scenario, Rohan paid the government dues to save his property, even though he was not legally obligated to do so. A quasi-contract is a legal concept that allows for the recovery of benefits conferred on another party under certain circumstances, even in the absence of a formal contract.
