Plz explain what is COPY RULE. Thanks

Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization that flourished at the same time as the civilizations in the Nile delta and the river valleys of the Tigris and Euphrates.

A) that flourished at the same time as the civilizations [so far good]
B )that had flourished at the same time as had the civilizations [had flourished refers to the earlier past action, it makes no sense with the modifier at the same time ]
C )that flourished at the same time those had[plural those doesn't have a proper referent]
D )flourishing at the same time as those did [plural those doesn't have a proper referent]
E) flourishing at the same time as those were[plural those doesn't have a proper referent]

My answer is A

+1 for A
bcuz the verb for two parts are exactly the same (flourished)and we can omit the second one
choice b is wrong since the use of past perfect in that sentence is wrong while i think the comparison structure is correct (... had flourished..... as had ......)

OA is A
