This question addresses the procedural requirements for distributing official orders within a specific administrative or legal context. The correct answer is SDEO.
The SDEO (Sub-Divisional Executive Officer) is typically a key administrative authority responsible for the implementation and enforcement of such orders. Therefore, they are a necessary recipient for official communication to ensure proper action and record-keeping.
Chairperson (A) might be a higher authority, but not necessarily the direct recipient for operational distribution of the order for enforcement.
A Whistle-blower (C) initiates a complaint but is not usually a formal party for receiving the final order for enforcement purposes, beyond being the aggrieved party.
The Media (D) is for public dissemination, not for official procedural distribution of an order within the administrative chain.
