Step 1: Understanding the Concept:
Bearer debentures are those where the company does not maintain a record of the holder. The person who possesses the document is considered the owner.
Step 2: Detailed Explanation:
- Because they are not registered, they are considered negotiable instruments (A).
- They can be transferred simply by handing them over to someone else, known as "mere delivery" (C).
- Interest is paid to whoever presents the interest coupons, regardless of who they are (D).
- A "deed of transfer" is a formal legal document required for Registered Debentures, not for Bearer ones. Therefore, (B) is incorrect.
Step 3: Final Answer:
Option (B) is not a characteristic of Bearer Debentures.
