Step 1: Understand the question is asking about the largest human cell by diameter, focusing on eukaryotic cells in the human body.
Step 2: Recall that the oocyte (egg cell) is known for being unusually large compared to most other human cells, often visible to the naked eye.
Step 3: Compare typical sizes of the options: erythrocytes are small (about 7-8 micrometers), skeletal muscle fibers are long but not necessarily large in diameter, and neuron cell bodies vary but are generally smaller than oocytes.
Step 4: Recognize that the oocyte's large diameter is due to its role in reproduction, containing nutrients and organelles to support early development.
Step 5: Conclude that among the given options, the oocyte is the largest cell by diameter in the human body.
