Answer: c) Sundari
Explanation
- Sundari Tree (Heritiera fomes): The Sundarbans Delta gets its name from the abundant Sundari trees found throughout its tidal mangrove forests.
- Adaptation: It is a mangrove species uniquely adapted to high-salinity, marshy, and tidally flooded soil. It features specialized aerial roots called pneumatophores (breathing roots) that project vertically above the mud and water level to absorb oxygen directly from the air.
Overview of Other Options
- a) Teak (Tectona grandis): A high-value hardwood tree species predominant in tropical deciduous and dry forests (found extensively in Central and South India).
- b) Sal (Shorea robusta): A major hardwood tree typical of moist and dry deciduous forests across the Sub-Himalayan belt, Central India, and Eastern Ghats.
- d) Banyan (Ficus benghalensis): The national tree of India, known for its extensive aerial prop roots, commonly found across the Indian plains.
