Which sentence is a run-on sentence?

A. A camel can go without water for days and days, he stores water in the hump on his back.

Run-on sentences are usually the equivalent of two sentences stuck together without proper punctuation. The sentence above should be:

"A camel can go without water for days and days. He stores water in the hump on his back."

This seperates the sentence into two parts: one sentence stating the fact, and the other justifying it.
