The Competition Act was passed by the Indian Parliament in 2002 and received presidential assent in January 2003. However, it was not fully enforced until later years, with various sections coming into effect at different times. Since the question asks for the year of enforcement and the options provided do not include 2002 or the specific implementation years, 'None of these' is the technically correct choice.

According to the Sale of Goods Act, when a contract is made for the sale of goods by both sample and description, it is a statutory condition that the bulk of the goods must correspond with both the sample and the description. Failure to meet either requirement constitutes a breach of condition, allowing the buyer to reject the goods.

Section 3 of the Competition Act, 2002, prohibits anti-competitive agreements. It states that no enterprise or association of enterprises shall enter into any agreement in respect of production, supply, distribution, storage, acquisition, or control of goods or provision of services which causes or is likely to cause an appreciable adverse effect on competition within the market. Agreements that violate this section are declared void.

The Sale of Goods Act 1979 is a piece of legislation primarily enacted to regulate the sale of goods and protect the interests of consumers by establishing clear legal rights and obligations for both buyers and sellers in commercial transactions.

An agreement to sell is an executory contract. It becomes a sale when the property in the goods is transferred from the seller to the buyer. This transfer occurs when the specified time period expires or when the conditions stipulated in the agreement are satisfied by the parties involved.

According to the Sale of Goods Act, in an unconditional contract for the sale of specific goods in a deliverable state, the property in the goods passes to the buyer at the time the contract is made. This transfer of ownership occurs regardless of whether the payment of the price or the physical delivery of the goods is postponed to a later date.

Section 6 of the Sale of Goods Act clarifies that the subject matter of a contract of sale may be either existing goods, which are owned or possessed by the seller, or future goods, which are to be manufactured or acquired by the seller after the contract is made.

To be patentable, an invention must meet three main criteria: novelty, non-obviousness (inventive step), and industrial applicability. Novelty is the most fundamental requirement, meaning the invention must be new and not part of the 'prior art' or previously disclosed to the public anywhere in the world before the filing date.

The Sale of Goods Act 1979 is a fundamental piece of legislation that regulates the formation and performance of contracts for the sale of goods, ensuring that commercial transactions are conducted with clear legal standards regarding ownership and quality.

A conditional sale agreement is a contract where the buyer takes possession of the goods, but the legal title or ownership remains with the seller until the final installment is paid. While hire purchase is similar, the term 'conditional sale' specifically highlights the condition of ownership transfer upon full payment, distinguishing it from standard credit sales where ownership transfers immediately.
