Options

A. It is easy to collect and least expensive
B. Its size is convenient for dissection
C. It is non-poisonous
D. All

Answer

### Step-by-Step Solution:

1. **Introduction to Frogs**:
- Frogs are amphibians that are commonly used in biological studies due to their unique physiological and anatomical features.

2. **Easy to Collect and Inexpensive**:
- Frogs are widely available in various environments, making them easy to collect for study. Additionally, they are generally inexpensive compared to other laboratory animals, making them accessible for educational institutions.

3. **Convenient for Dissection**:
- The size of frogs is suitable for dissection, allowing students to easily observe and study their internal structures. This hands-on experience is valuable in understanding anatomy and physiology.

4. **Non-Poisonous Nature**:
- Frogs are non-poisonous, meaning they do not pose a risk of toxicity to students during dissection or handling. This safety factor is crucial in a classroom setting.

5. **Dual Purpose**:
- Studying frogs not only provides educational benefits but also contributes to ecological balance by controlling their population in the environment. This dual purpose enhances the relevance of studying frogs in classrooms.

6. **Conclusion**:
- Considering all these factors, frogs are deemed suitable for classroom studies. They are easy to collect, convenient for dissection, non-poisonous, and provide a valuable learning experience that parallels human anatomy.

### Final Answer:
Frogs are suitable for classroom studies because they are easy to collect and inexpensive, convenient for dissection, non-poisonous, and provide a dual purpose of ecological balance and educational value.
