Jon was constantly coughing, and all this was the result of extremely low levels of oxygen due to which his brain was also not working properly.

<span>The question is asking us to answer Which sentence uses commas correctly?. We see here that Savannah is the name of the city and that the city is already mentioned - the name is an extra information. You could for example say "The southern city is a beautiful place".
