The correct sequence of arrangements of segments in the leg of cockroach is

Options

A. coxa, femur, trachanter, tibia and claws
B. coxa, trochanter, femur, tibia, tarsus and claws
C. coxa, tibia, femur, plantulae and claws
D. none

Answer

To determine the correct sequence of arrangements of segments in the leg of a cockroach, we need to analyze the structure of the cockroach's leg. Here’s a step-by-step solution:

### Step 1: Identify the segments of the cockroach leg
The cockroach leg consists of several segments, which include:
- Coxa
- Trochanter
- Femur
- Tibia
- Tarsus (which includes claws)

### Step 2: Understand the function of each segment
- **Coxa**: This is the first segment that connects the leg to the body of the cockroach.
- **Trochanter**: This segment acts like a knee joint, allowing for bending.
- **Femur**: This segment is analogous to the thigh in humans and is responsible for supporting the leg.
- **Tibia**: This segment resembles the lower leg or shin and is involved in movement.
- **Tarsus**: This segment acts like the ankle and foot, and it includes the claws that help in gripping surfaces.

### Step 3: Arrange the segments in the correct order
Based on the anatomical structure and function of each segment, the correct sequence from the body to the end of the leg is:
1. Coxa
2. Trochanter
3. Femur
4. Tibia
5. Tarsus (which includes the claws)

### Conclusion
Thus, the correct sequence of arrangements of segments in the leg of a cockroach is:
**Coxa, Trochanter, Femur, Tibia, Tarsus, and Claws.**

The correct answer is **Option B**.
