• A. Wuchereria bancrofti
• B. Ancylostoma duodenale
• C. Trichinella spirals
  
• D. None of the above

Answer 1

The correct option is A Wuchereria bancrofti

Filarial worms and their larvae are parasitic thread-like round nematodes that cause a group of a tropical infectious disease called filariasis. The larvae are transmitted to humans through a mosquito bite. They are vectored by arthropods, mature and mate in specific host tissues, and produce microfilariae. The lymphatic filariae Wuchereria bancrofti and Brugia malayi reside in lymphatics.

Therefore, the correct answer is option A.
