Explanation:

2 and 3 only Deltas shrink due to lack of sediments and not due to huge amount of sediments. A proliferation of large dams that starve deltas of sediment, groundwater mining that causes land compaction, and artificial levees that affect river courses, have been responsible for the subsiding of major Indian deltas including Ganga-Brahmaputra, Krishna-Godavari, Brahmani and Mahanadi.
