Step 1: Recall the Negotiable Instruments Act, 1881.
The Negotiable Instruments Act, 1881 is the primary legislation governing negotiable instruments in India and defines which documents qualify as such.
Step 2: List the recognized negotiable instruments.
Under Section 13 of the Act, only three instruments are recognized: (a) Promissory Note, (b) Bill of Exchange, and (c) Cheque. All three are transferable financial documents used in trade and commerce.
Step 3: Identify the odd one out.
A Sale Deed transfers ownership of immovable property and is governed by the Transfer of Property Act, 1882, not the Negotiable Instruments Act.
