Blood sucking hookworms inhabit 1000 million people worldwide
B
Correct answer
Explanation
This statement is false. While hookworms are a significant global health problem affecting 500-600 million people worldwide according to WHO estimates, the figure of 1000 million (1 billion) is exaggerated. The highest prevalence is in tropical and subtropical regions with poor sanitation, particularly in sub-Saharan Africa, China, and parts of Southeast Asia.
