Final Answer :
B
Explanation :
Sensory neurons are primarily unipolar, which means they have a single process extending from the cell body. However, some sensory neurons, especially those involved in special senses like vision, are bipolar, having one axon and one dendrite. This diversity allows for the transmission of different types of sensory information.
