The Ranchi Bench of the Patna High Court became the separate High Court of Jharkhand on which date?

The correct answer is C, 15 November 2000. Jharkhand was carved out of Bihar on that date under the Bihar Reorganisation Act, 2000, and the Ranchi Bench of the Patna High Court became the High Court of Jharkhand at Ranchi. The Patna High Court has had no Bench outside Patna since then.

Option A, 1 November 2000, is the date on which Chhattisgarh was separated from Madhya Pradesh and the High Court of Chhattisgarh at Bilaspur came into being. Option B, 9 November 2000, is the date on which Uttarakhand was separated from Uttar Pradesh and the High Court of Uttarakhand at Nainital was established. The three states were created within a fortnight of each other in the same year, and examiners exploit that closeness, so the order to remember is Chhattisgarh on 1 November, Uttarakhand on 9 November and Jharkhand on 15 November 2000. Option D, 1 March 2000, has no significance here, though 1 March 1916 is the day the Patna High Court began sitting.
