Tripedal locomotion occurs in

Options

A. Kangaroo
B. Cockroach
C. Snail
D. Earthworm.

Answer

**Step-by-Step Solution:**

1. **Understanding Tripedal Locomotion:**
- Tripedal locomotion refers to movement using three legs. This type of locomotion is typically observed in certain arthropods.

2. **Identifying the Organisms:**
- The question provides four options: Ganga, Cockroach, Snail, and Earthworm. We need to analyze each option to determine which one exhibits tripedal locomotion.

3. **Analyzing Each Option:**
- **Ganga:** This is not an organism but a river, so it cannot exhibit locomotion.
- **Cockroach:** Cockroaches are arthropods with three pairs of jointed legs. They can exhibit tripedal locomotion by using three of their six legs for movement.
- **Snail:** Snails move using a large muscular foot and do not have legs in the same sense as arthropods. They do not exhibit tripedal locomotion.
- **Earthworm:** Earthworms are annelids and use longitudinal and circular muscles for movement. They do not have legs and therefore do not exhibit tripedal locomotion.

4. **Conclusion:**
- Based on the analysis, the correct answer is that tripedal locomotion occurs in the **Cockroach**.

**Final Answer:**
Tripedal locomotion occurs in **Cockroach**.
