The ICSI study material notes that the latest Constitutional Amendment is the 104th Amendment Act. On which date did it come into force?

1. The ICSI text records that the latest amendment to the Constitution was the **104th Amendment**, which came into force on **21-01-2021**. 2. The 104th Amendment extended the reservation of seats for SCs and STs in the Lok Sabha and State Legislative Assemblies for another ten years (until January 2030) and abolished the nominated Anglo-Indian seats. 3. The dates in options A and B are too early — the 103rd Amendment (EWS reservation) came into force in early 2019. Option D is too late. 4. Memorising the headline amendment alongside the date helps in objective-style entrance questions. _Source: ICSI CS Executive — Lesson 2, Bill section (viii), p. 77._
