Answer:
I believe it is D
Step-by-step explanation:
I think this because in the excerpt:
Egyptian scripts were replaced with Coptic, which included six demotic characters. In the ninth century, Arab scholar Abu Bakr Ahmad Ibn-Wahshiyah was able to partly decipher the hieroglyphs by comparing them to Coptic. But in the eleventh century, it too was replaced, by Arabic. The link was once again severed. For centuries, Western scholars tried to decipher the hieroglyphs, with little success. They were working under a false hypothesis, that the hieroglyphs were pictograms, with each symbol representing an object or an idea.
(I underlined and bolded clues that led to my conclusion)
The summary of this excerpt would be: D- For a long time, scholars from different places tried to figure out the meaning of hieroglyphs, but they mistakenly believed each hieroglyph was a symbol.
