The trees of tropical rainforest have buttress roots because :
they help to provide aeration to soils
the organisms found in the buttresses have a symbiotic relationship
the trees belong to gramineae family
the buttresses have to bear the mechanical load of hardwoods

Answer is Wrong!

The correct answer is D. Buttress roots provide structural support to large trees in unstable tropical rainforest soils, helping them bear their mechanical load and resist toppling.
Tropical rainforest soils are typically shallow, nutrient-poor, and sometimes waterlogged. Trees in these environments often do not develop deep taproots for stability. Instead, they rely on widespreading, shallow root systems and buttress roots at the base of the trunk. Buttress roots are large, triangular supports that spread horizontally and vertically, increasing the tree’s base area and providing stability against strong winds and the weight of the canopy and epiphytes.
