The Correct Option is A
Solution and Explanation
Concept:
Water hyacinth (Eichhornia crassipes) is an aquatic plant known for its rapid growth and invasive nature. It is often referred to as the “terror of Bengal” due to its spread in Indian water bodies.
Step 1: Recall origin of the species. Water hyacinth is native to the tropical regions of South America, particularly the Amazon basin. \[ \text{Native region} = \text{Amazon basin} \]
Step 2: Understand its spread. It was introduced to many parts of the world as an ornamental plant but became invasive due to its rapid multiplication.
Step 3: Analyze the options.
• (A) Amazon basin → Native region \checkmark
• (B) Central Europe → Not native $\times$
• (C) Central Africa → Not native $\times$
• (D) Bay of Bengal → Not native $\times$
Step 4: Conclusion. Thus, the native place of water hyacinth is: \[ \text{Amazon basin} \]
