Read the passage below carefully and answer the question that follows:
The mangroves of the Niger Delta constitute one of the largest continuous wetland ecosystems in West Africa, serving as critical breeding grounds for coastal fisheries. In recent decades, industrial urbanization and timber harvesting have severely fragmented these littoral forests. In 2018, environmental researchers initiated a restoration scheme relying on Nypa palm eradication coupled with indigenous Rhizophora mangrove replanting. While local communities originally utilized Nypa palm fronds for temporary thatch roofing, the species rapidly outcompeted native flora, offering zero root density for coastal erosion defense. Surprisingly, recent surveys revealed that while Rhizophora survival reached 78% in community-managed zones, commercial plots recorded only a 42% survival rate due to soil compaction from heavy machinery.
According to the passage, which of the following is an explicit drawback of the Nypa palm?
- It fails to provide the root density necessary to protect against coastal erosion.Answer
- BIt caused severe soil compaction that reduced mangrove survival to 42%.
- CIt recorded a reduced survival rate of 42% in community-managed zones.
- DIt prevented local inhabitants from constructing temporary thatch roofs.
