राज्याच्या कोणत्याही कारभारासंबंधिच्या अप्रकाशित शासकीय दप्तरामधून उपलब्ध होणारा कोणताही पुरावा देण्यास परवानगी :

The correct answer is Option D (Officer at the Head of the Department Concerned).

Key Points:
• Section 123 of the Indian Evidence Act, 1872:
• Titled 'Evidence as to affairs of State', Section 123 mandates:
• > *"No one shall be permitted to give any evidence derived from unpublished official records relating to any affairs of State, except with the permission of the officer at the head of the department concerned, who shall give or withhold such permission as he thinks fit."*
• This statutory privilege protects core state secrets and sensitive administrative communications from compulsory disclosure in judicial proceedings.
• The authority to grant or withhold permission rests strictly with the officer at the head of the department concerned (such as the Secretary of the Ministry/Department).
• Hence, Option 4 is the precise legal phrasing.
• Key Takeaway: Under Section 123 of the Indian Evidence Act, evidence from unpublished state records requires permission from the Head of the Department Concerned.
