Which one of the following is not a public document ?

Under the Indian Evidence Act, 1872, documents are classified as either public or private. According to Section 74, public documents include:

• Documents forming the acts or records of the acts of the sovereign authority, official bodies and tribunals, and public officers (legislative, judicial, and executive).
• Public records kept in any State of private documents (e.g., a registered sale deed).

Section 75 states that all other documents are private. A will is a private document created by an individual. Even if a will is registered, the document itself remains private; only the entry in the register is a public record. An unregistered will has no public record associated with it and is strictly a private document. Therefore, option B is the correct answer as it is not a public document.
