Step 1: Background of criminal procedure reform.
In 2023, India replaced its three major colonial-era criminal laws as part of a comprehensive legal reform.
Step 2: Identify the correct replacement.
The Code of Criminal Procedure, 1973 (CrPC) was replaced by the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS). It came into effect on 1 July 2024.
Step 3: Eliminate distractors.
The Bharatiya Nyaya Sanhita replaced IPC, and the Bharatiya Sakshya Adhiniyam replaced the Indian Evidence Act.
