On whose recommendation, Election Commissioner or Regional Election Commissioner shall be removed from the office?

The Election Commissioners (including the Chief Election Commissioner and other Election Commissioners) can only be removed from office in a manner similar to a Supreme Court judge - through impeachment by Parliament on grounds of proven misbehavior or incapacity. While the President acts on the recommendation, the actual removal process requires parliamentary proceedings. The question specifically asks about the recommendation authority for removal, and the Chief Election Commissioner's role is established in the constitutional framework. Option D (None of the above) would be incorrect if the question is interpreted as asking about the procedural recommendation.
