Which of the following statements are appropriate to Mangrove Sites? 1. Mangrove plants require appropriate mix of saline water and freshwater, 2. Mangrove plants require mudflats to enable it to grow and develop. 3. Mangrove plants are found in the inter-tidal zones of sheltered coasts. 4. Mangrove vegetation has been reported in all the coastal States including Andaman and Nicobar Islands. Select the correct answer using the code given below,

Mangrove ecosystems are specialized littoral plant formations found in tropical and subtropical sheltered coastlines [5]. They thrive in the inter-tidal zones where they require a mix of saline and freshwater, often found in estuaries and deltas [4]. The reduction in freshwater flow is known to decrease species diversity, highlighting the importance of this salinity balance. These plants specifically require mudflats and tidal flats with fine sediments to grow and develop their complex root systems [4]. In India, mangroves are distributed across all coastal states and island territories, including the Andaman and Nicobar Islands [2]. While the east coast features large deltas like the Sundarbans and Godavari, the west coast contains scrubby mangroves in the intertidal regions of Gujarat, Maharashtra, Goa, Karnataka, and sparse vegetation in Kerala [3]. Thus, all four statements accurately describe mangrove site requirements and their distribution in India.
