I would definitly go with A
You can add re- to get redust which means to dust again
The correct answer is D.
Analyzing the artist's intent is crucial to determining the success of the recreation.
Because a different medium is used, the effect will likely be different than the original. Understanding the artist's intent is necessary to understanding whether the artist was successful in recreating an original work in a different medium.
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 :)
