Explanation
Mangroves grow on mudflats (2), in the inter-tidal zones of sheltered coasts (3), and are reported from all coastal states including the Andaman & Nicobar Islands (4) — textbook characteristics of mangrove sites. Statement 1 is the odd one out: mangroves tolerate high salinity through salt exclusion and excretion, and do not require any specific mix of saline and fresh water. Hence 2, 3 and 4 only.
