(A) visible on many copper items, and is produced
(B) that is visible on many copper items, and which produces
(C) visible on many copper items, and produces
(D) that is visible on many copper items, and that produces
(E) which is visible on many copper items, and which is produced
Though I chose the correct answer, I have a question regarding the usage of 'like usage' here.
1. The part of the sentence after AND is
(Aerugo) is produced, like iron rust, over the course of time by the exposure of the metal to the oxygen in the atmosphere. ---->
Shouldn't 'like iron rust' touch the subject with which it is compared - we should place like iron rust immediately after the AND?2. Aerugo, also known as verdigris, is the green "bloom" visible on many copper items, and, like iron rust, is produced over the course of time by the exposure of the metal to the oxygen in the atmosphere.
--- in this sentence the part after AND is
(Aerugo) , like iron rust, is produced over the course of time by the exposure of the metal to the oxygen in the atmosphere.

Usage of comma + AND for joining 2 clauses- Exception to this rule (from
MGMAT forum -
https://www.manhattanprep.com/gmat/foru ... 10863.html)
"Standard usage permits a comma here because the first of the two parallel verbs introduces a pretty complicated clause, is the green "bloom" visible on many copper items, whose noun, items, might otherwise seem to be the first of the elements coordinated by and. The comma makes it clear that something earlier in the sentence must be parallel, and when we see that a verb follows and it's not hard to see what that first element is.
I'm not sure that this sentence would be hard to follow without the comma, I'm not sure that it's required, but it is permissible."
