Step 1: Understanding the Concept:
The question provides a legal definition of a specific type of transfer of immovable property and asks to identify it. This requires knowledge of the definitions provided in the Transfer of Property Act, 1882.
Step 2: Detailed Explanation:
The text in the question is a verbatim reproduction of the definition of a Mortgage as provided in Section 58(a) of the Transfer of Property Act, 1882.
Let's look at the other options for comparison:
- Sale (Section 54): Is a transfer of \textit{ownership} in exchange for a \textit{price} paid or promised.
- Gift (Section 122): Is a transfer of ownership made voluntarily and \textit{without consideration}.
- Lease (Section 105): Is a transfer of a \textit{right to enjoy} such property for a certain time in consideration for a price paid or promised (rent).
The key phrase in the question is "for the purpose of securing the payment of money". This is the essential characteristic of a mortgage, where an interest in property is transferred not absolutely, but as security for a debt.
Step 3: Final Answer:
The definition provided is the exact legal definition of a mortgage under the TPA. Therefore, option (C) is the correct answer.
