The correct Answer is:
To determine the type of neurons present in earthworms, we can follow these steps: 1. **Understand the Structure of Earthworms**: Earthworms belong to the phylum Annelida and have a segmented body structure. This segmentation is important for their nervous system organization. 2. **Identify the Types of Neurons**: Neurons in earthworms can be classified into two main types: sensory neurons and motor neurons. - **Sensory Neurons**: These neurons are responsible for carrying information from sensory receptors to the central nervous system (CNS). They help the earthworm respond to environmental stimuli. - **Motor Neurons**: These neurons transmit impulses from the CNS to the muscles or glands, enabling movement and action. 3. **Conclusion on Neuron Types**: Since earthworms possess both sensory and motor neurons, they have a mixed type of neurons. 4. **Final Answer**: Therefore, the correct answer to the question is (d) Mixed. ---
