If a question gives tides, salinity and Sundari tree as three clues, what will be the correct answer?

Correct answer: Mangrove forest

Mangrove forests develop along coasts, river mouths, tidal creeks, and deltas where seawater or salty water affects the soil. These places are regularly flooded and exposed by tides, so plants need special adaptations such as breathing roots and tolerance of salinity. The Sundari tree is a well-known mangrove species, especially associated with the Sundarbans. Thus, the three clues in the question point to the same coastal ecosystem rather than to an ordinary inland forest.

Option A is correct because tides, saline conditions, and the Sundari tree are characteristic clues for mangrove forests. Thorn forests are adapted to dry conditions, montane coniferous forests to cold highlands, and tropical deciduous forests to seasonal rainfall away from tidal salt water. In a clue-based question, matching all clues together is safer than focusing on only one word. Here every clue supports the mangrove answer.
