The correct Answer is:
To solve the question "Arterial heart is found in:", we will analyze the options provided and determine which organism possesses an arterial heart. ### Step-by-Step Solution: 1. **Understanding the term "Arterial Heart":** - An arterial heart refers to a heart structure that primarily consists of arteries and is typically found in certain invertebrates and some lower vertebrates. 2. **Evaluating the first option: Fish** - Fish possess a two-chambered heart, which consists of one atrium and one ventricle. Therefore, fish do not have an arterial heart. - **Conclusion:** Incorrect option. 3. **Evaluating the second option: Prawn** - Prawns, which are crustaceans, have an arterial heart. Their circulatory system is open, and they possess a heart that pumps hemolymph (a fluid equivalent to blood) through arteries. - **Conclusion:** Correct option. 4. **Evaluating the third option: Earthworm** - Earthworms have a closed circulatory system with five pairs of aortic arches, which function similarly to a heart but are not classified as an arterial heart. - **Conclusion:** Incorrect option. 5. **Evaluating the fourth option: Frog** - Frogs have a three-chambered heart, consisting of two atria and one ventricle. This structure does not qualify as an arterial heart. - **Conclusion:** Incorrect option. ### Final Answer: The correct answer is **Prawn** (Option 2), as it is the only organism listed that possesses an arterial heart. ---
