• D. Glial

Answer: (A)

Verified step by step guidance

1. Begin by understanding the structure of neurons, which are the basic building blocks of the nervous system. Neurons typically consist of a cell body, dendrites, and an axon.
2. Identify the different types of neurons based on their structure. The main types include unipolar, bipolar, and multipolar neurons.
3. Focus on bipolar neurons, which are characterized by having one dendrite and one axon. This structure is distinct from other types of neurons.
4. Consider the function and location of bipolar neurons. They are often found in sensory pathways, such as the retina of the eye, where they play a role in transmitting sensory information.
5. Review the options provided: Bipolar, Stem, Lens, and Glial. Recognize that 'Bipolar' is the term that matches the description of having a single dendrite and a single axon.
