Answer:
This paragraph reveals the following perception by Voltaire concerning Helvetius's writing:
D. It is unique but sometimes pretentious and showy.
Explanation:
It is sentence number 2 that shows how Voltaire appreciates the uniqueness in Helvetius's writing. Notice that Voltaire says he possesses a "fearless genius," and that his "work sparkles with imagination." There is something special, thus, about his writing, something Voltaire admires. However, sentence 4 reveals there is also something to be criticized. It is Voltaire's opinion that Helvetius's writing can be showy and pretentious. He advises him not to "fall into the grandiose." Keeping it simple, using the "right word" and "true similes" is, to Voltaire's mind, better.
