B Correct answer
Explanation

Elephantiasis is caused by parasitic nematodes (roundworms) called Wuchereria bancrofti, which belong to the phylum Nematoda. These thread-like worms block the lymphatic vessels, causing extreme swelling and thickening of the skin and underlying tissues, particularly in the lower limbs. The other phyla listed do not contain species that cause this condition.
