  • (c) Naupada Swamp: A local coastal swamp/wetland, but not the standard large-scale example cited for repeated falls in sea level. Verdict: Incorrect.
  • (d) Rann of Kutch: The Rann is widely cited as a former shallow sea/lagoon area affected by repeated marine regression, leaving behind extensive marshy salt flats. Verdict: Correct.
