Not attemptedCorrect Answer: (d) The mangrove trees do not get uprooted by storms and tides because of their extensive roots
Mangrove trees possess inter-locking prop and pneumatophore roots that anchor them firmly in soft, water-logged soils; this root network disperses wave energy so the trees are rarely uprooted by cyclones or tsunami surges. The other options describe features that are not the primary physical mechanism of protection.
