B Correct answer
Explanation

Neurons are the longest cells in the human body, with axons extending from the spinal cord to the toes (up to 1 meter). Lymphocytes, osteocytes (bone cells), and leucocytes (white blood cells) are microscopic cells without such elongated processes. The neuron's length enables rapid signal transmission across distances.
