Step 1: Understanding the Concept:
The Chief Justice of India (CJI) is the head of the Supreme Court of India and the highest-ranking officer of the Indian federal judiciary. The President of India appoints the CJI based on the recommendation of the outgoing CJI and the seniority principle.
Step 2: Detailed Explanation:
1. Justice D.Y. Chandrachud: He served as the 50th CJI from November 2022 to November 2024.
2. Justice Sanjiv Khanna: He succeeded Justice Chandrachud and took oath as the 51st Chief Justice of India on November 11, 2024. His tenure continues through 2025.
3. Justice B.R. Gavai: He is next in line to succeed Justice Khanna as per the seniority list.
4. Justice Surya Kant: He is also in the pipeline for 2025/2026.
Since the question asks for the appointee relevant to the 2025 timeline among the options provided, Justice Sanjiv Khanna is the primary incumbent for that period.
Step 3: Final Answer:
The correct choice is Justice Sanjiv Khanna. Thus, Option (B) is the correct choice.
