The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Giardia:** - Giardia is a unicellular eukaryotic organism that causes a disease known as Giardiasis. It primarily affects the small intestine of humans and other animals. 2. **Identifying the Structure:** - Giardia has a specialized structure known as the "ventral disc." This disc is crucial for its attachment to the host's intestinal lining. 3. **Locating the Attaching Disc:** - The attaching disc of Giardia is located on the ventral side of the organism. The ventral side refers to the underside of the organism, which is in contact with the host's intestinal wall. 4. **Determining the Position:** - The attaching disc is positioned anteriorly, meaning it is located towards the front of the organism. This allows Giardia to effectively attach to the anterior part of the small intestine. 5. **Selecting the Correct Option:** - Given the options provided: - (1) Anteriorly over dorsal side - (2) Posteriorly on dorsal side - (3) Anteriorly over ventral side - (4) Posteriorly on ventral side - The correct answer is option (3): Anteriorly over ventral side. **Final Answer:** The attaching disc of Giardia occurs anteriorly over the ventral side. ---
