Step 1: Understanding the CAA.
The Citizenship Amendment Act (CAA) was passed in India in 2019. It provides a pathway to Indian citizenship for non-Muslim refugees from Pakistan, Bangladesh, and Afghanistan.
Step 2: Implementation in Assam.
The CAA has been implemented in Assam and some other parts of India, although it has been met with protests, especially in the northeastern states.
Step 3: Verifying the Options.
Option (1): West Bengal has had protests, but the act is not exclusively implemented there.
Option (2): Assam is the correct answer, where there was significant opposition to the Act.
Option (3): Kerala also had protests but did not specifically implement the Act.
Option (4): Uttar Pradesh has seen protests but is not a key state for CAA implementation.
