The Correct Option is C
Solution and Explanation
\textit{Giardia} is a flagellated protozoan parasite belonging to phylum Mastigophora. It causes giardiasis, a diarrheal disease in humans.
The organism has a bilaterally symmetrical pear-shaped body with:
- Two nuclei
- A ventral adhesive disc
- Eight flagella arranged in four pairs (anterior, posterior, caudal, and ventral)
These flagella are essential for locomotion and attachment to the host’s intestinal wall. The number of flagella is a distinctive feature used in classification and identification of the organism.
