Under the Sale of Goods Act, if the property (ownership) in the goods has already passed to the buyer, the seller cannot withhold delivery unless they retain a right of lien or stoppage in transit. Withholding delivery is generally a right available when ownership has not yet transferred to the buyer.

The Latin phrase 'Caveat Emptor' translates to 'let the buyer beware.' It is a fundamental principle in contract law stating that the buyer is responsible for checking the quality and suitability of goods before making a purchase. Unless there is an express warranty or fraud by the seller, the seller is not liable for defects discovered after the sale is completed.

An unpaid seller has several remedies under the Sale of Goods Act, including the right to sue for the price, sue for damages for non-acceptance, sue for repudiation of the contract, and claim interest on the amount due.

Under the TRIPS Agreement and the laws of most jurisdictions, the standard term of patent protection is 20 years from the date of filing the application, provided that all maintenance fees are paid and the patent remains in force.

An invention is legally defined as a new product or a new process that involves an inventive step and is capable of industrial application. To be patentable, the invention must be non-obvious to a person skilled in the relevant field and must provide a practical, useful solution to a technical problem.

Refusal to deal, as defined under the Competition Act, 2002, includes any agreement which restricts or is likely to restrict, by any method, the persons or classes of persons to whom goods are sold or from whom goods are bought. This provision aims to prevent anti-competitive practices that limit market access or restrict trade channels for specific entities.

Under the Sale of Goods Act, goods are generally classified as existing (specific or ascertained) and future goods. While specific, ascertained, and un-ascertained goods refer to the state of identification of existing goods, 'future goods' refers to goods to be manufactured or acquired by the seller. The answer key identifies 'Future goods' as the odd one out, likely due to the distinction between existing and non-existing goods.

Caveat emptor is waived when the buyer makes their specific purpose known to the seller and relies on the seller's skill or judgment. If the seller is in the business of supplying such goods, there is an implied condition of fitness for that purpose. If these conditions are met, the seller assumes responsibility for the suitability of the goods provided.

The right of stoppage in transit allows an unpaid seller to resume possession of goods. This right ends when the buyer or their agent takes delivery, when the buyer rejects the goods, or when the carrier acknowledges the buyer's right to hold the goods, effectively ending the transit phase.

Statement I is correct as stoppage in transit only applies when goods are in transit and not in the seller's possession. Statement II is correct because an unpaid seller has a lien or right of resale when they retain possession. Statement III is technically incomplete as it depends on the contract terms, but in the context of standard legal testing, C is the provided answer.
