Answer

Answer:

It may take me months, if not years, to train for a marathon.

Brief Explanations:

The phrase "if not years" is non - essential and correctly offset by commas. In the second option, the comma after "named" is incorrect. In the third option, "who lives in another state" is a restrictive clause and doesn't need commas around it. In the fourth option, the commas around "to a late - night rock concert" are incorrect as it's not a non - essential phrase.
