The two answers that you see most often are nerve cell and ovum.
Both are correct.
1. the nerve cells that make up sensory nerves have their cell bodies in the dorsal root ganglion located in the back and the have extensions (dendrites) that reach to the area sensed (all the way to the toes. (many millimeters long but very, very thin).
2. The cell body of the ovum is the round and had the largest volume of any cell.

[APPLAUSE]
D: Good evening, Yaël.
Y: Good evening, Don.
D: Tonight we are here to present some very special awards to some outstanding body parts.
Y: Yes, these parts of the human body have really distinguished themselves. Shall we start, Don?
D: Let's. Our first award is for the body's largest organ. Would you like to do the honors, Yael?
Y: Thank you, Don. This is so exciting. This award goes to...the skin!
[APPLAUSE]
D: Did you know, Yael, that if you were to stretch out an adult's skin, it would be about 2.4 square yards?
Y: No, I didn't, Don. That's pretty big! Our next award is for the hardest substance in the human body. Don?
D: And the winner is...Tooth enamel!
[APPLAUSE]
Y: Wow! The enamel has to be very hard to protect the teeth for a lifetime of chewing.
D: Our final award this evening is for the biggest cell in the human body.
Y: And the judges say...oh, this seems like it could be a controversial decision since the biggest cell is not in every body, it's only the bodies of females...it's the egg cell!
[APPLAUSE]
Y: Ah! It may be only in the female body, but every one of us started out as an ovum. Once a sperm fertilizes it, it can grow into a baby inside the mother.
D: And then it has it's own body parts.
Y: Well, what a wonderful evening it's been.
D: Yes, and what dedicated body parts we've honored.

The largest cell in the human body is the ovum, the female sex cell. The ovum is about 1000 micrometers, or one millimeter, in diameter. The ovum needs this size as nourishment before it implants itself in the uterus. It becomes this large by this means: In meiosis, there are two stages. In the first stage, the nucleus divides in a way that reduces the number of chromosomes to half in each nucleus generated. In the second stage, the sister chromosomes separate, largely resemble the meitosis. When the nucleus of the cell that will become the ovum divides the first time, it simply expells one nucleus. The second time, it does the same. This leaves one huge ovum and three little cells, called polar bodies, outside. (The expelled nucleus divides again, too.) The ovum does not release the second nucleus until it is fertelized. The tiny cells quickly die, because they have no organelles.

Actually, those who are saying ovum are probably wrong. The largest cell in the body would have to be motor or sensory neurons to the feet muscles and toes. Keep in mind the axons of these cells stretch from the spinal cord, all the way to the distal end of the feet.

egg cell
I think a chicken egg is one cell too.
