I would say c. timelessness of the message.
Why? Because:
a) your piece of writing has to have a message - if there is no message, there is no point in writing it.
b) you have to have an intended audience you are writing for - it is not the same writing something for your friends, little brother/sister, professor or a potential employer.
c) the format of the message is important because of the previous factor and because the format usually affects the reception of the writing; nobody will be interested in your text if you write it without commas, fullstops, capitalized letters at the beginning of the sentence, or for example, without spaces between the words because it would be too confusing.
While, the timelessness is not as important. You are writing it for a special purpose now, and if it is good it might become timeless. But there are probably many great works (poems, scientific papers, novels, etc.) that were lost or forgotten, but that does not mean they were not great or significant.
Hope my answer is not too confusing :)
Book - Silent Spring
Author - Rachel Carson
Textual evidence -
"This town does not actually exist, but it might easily have a thousand counterparts in America or elsewhere in the world. I know of no community that has experienced all the misfortunes I describe. Yet every one of these disasters has actually happened somewhere, and many real communities have already suffered a substantial number of them. A grim specter has crept upon us almost unnoticed, and this imagined tragedy may easily become a stark reality we all shall know."
Explanation:
Rachel Carson explains about a town with nature's beauty, where plants, animals, birds and human all lived in harmony. Suddenly due to some evil effects, everything changed. Humans, children died to strange sickness. Birds disappeared, hen did not lay eggs, apple trees bear no fruits, rivers and streams dried, fishes died. A white powder showed on the roofs sprayed by people which caused destruction.
Rachel Carson explains further that the town she describes does not actually exist to make the readers understand the effects of the chemicals and insecticides caused mass destruction due to extensive use causing the nature to perish slowly. She insisted on taking necessary steps to notice the changes before it becomes a dark reality.
