Enterobiasis diseases is caused by

The correct option is Pinworm.

Step-by-step Explanation:

1. Understanding Enterobiasis:
Enterobiasis is a highly common parasitic infection primarily affecting the human gastrointestinal tract, especially in children. It is characterized by intense itching in the perianal region, particularly at night.

2. Identifying the Causative Agent:
The disease enterobiasis is caused by a specific type of parasitic nematode (roundworm) known scientifically as Enterobius vermicularis.

3. Common Name of the Parasite:
In common terminology, Enterobius vermicularis is widely referred to as the pinworm (or threadworm) due to the female worm's long, pointed tail which resembles a pin. Therefore, enterobiasis is commonly known as a pinworm infection.

4. Evaluating Other Options:
- Hookworm: Causes hookworm infection (ancylostomiasis or necatoriasis), not enterobiasis.
- Filarial worm: Causes lymphatic filariasis (elephantiasis).
- Roundworm: While pinworms are technically a type of roundworm, the term "roundworm" in medical contexts often specifically refers to Ascaris lumbricoides (causing ascariasis), making "Pinworm" the most precise and correct choice among the options.
