Understanding the Sale of Goods Act, 1930:
The Sale of Goods Act, 1930 is a legislation that governs the sale of goods in India. It defines the rights and obligations of buyers and sellers in a contract of sale. According to this act, a contract of sale is an agreement where the seller transfers or agrees to transfer the property in goods to the buyer for a price.

Transfer of Property in Goods:
The transfer of property in goods is a crucial aspect of a contract of sale. It refers to the transfer of ownership or title of the goods from the seller to the buyer. Once the property in goods is transferred, the buyer becomes the legal owner of the goods and acquires all the rights and responsibilities associated with the ownership.

Options Explained:
a) Possession: Possession refers to the physical control or holding of the goods. While possession can be transferred from the seller to the buyer, it does not necessarily mean that the property in goods has been transferred. The seller may retain ownership while allowing the buyer to possess the goods temporarily.

b) Control: Control refers to the power or authority to determine the use or disposition of the goods. Similar to possession, control can be transferred without transferring the property in goods. For example, a seller may grant the buyer the right to control the goods under certain conditions, but retain ownership.

c) Rights: Rights in the goods can include various legal entitlements such as the right to use, sell, or dispose of the goods. While the buyer may acquire certain rights in the goods through a contract of sale, it does not necessarily mean that the property in goods has been transferred.

d) Property: Property in goods refers to the ownership or title of the goods. When the property in goods is transferred from the seller to the buyer, the buyer becomes the legal owner of the goods. This means that the buyer has full rights and control over the goods, including the right to use, sell, or dispose of them.

Therefore, under the Sale of Goods Act, 1930, the seller in a contract of sale transfers the property in the goods to the buyer for the price.
