This is a tricky one

We can initially eliminate A, B since "with it the Aramaic script" is necessary as opposed to "Aramaic script with it"; if this weren't the case, the following clause would modify "it" instead of "Aramaic script," which is not correct.

Choice E can be eliminated since it is awkward and doesn't form a complete sentence. Now here's the real trick... I was initially leaning toward D, but this is a trap! Here's the question to ask.. "What derive(s) from the Aramaic script?" The answer is "northern and southern alphabets," which is a plural answer. This means that "derive" has to be used instead of "derives.

That would put us at choice C.

Guys why (E) wrong is not clear..Please elaborate
