A. Columbus was the Incan highway, which, over 2,500 miles long and extending --- which referring the object ‘the highway’ starts a subordinate clause having no verb; a fragment.
B. Columbus was the Incan highway, over 2,500 miles in length, and extended --- bad parallelism on the connector ‘and’ in which one side is a just a phrase and the other side is a clause
C. Columbus, the Incan highway, which was over 2,500 miles in length and extended --- a fragment; no verb for the road system.
D. Columbus, the Incan highway, being over 2,500 miles in length, was extended – meaning awfully changed as if it was extended because it was 2500 miles long.
E. Columbus, the Incan highway was over 2,500 miles long, extending--- Correct structure.
B. Columbus was the Incan highway, over 2,500 miles in length, and extended --- bad parallelism on the connector ‘and’ in which one side is a just a phrase and the other side is a clause
C. Columbus, the Incan highway, which was over 2,500 miles in length and extended --- a fragment; no verb for the road system.
D. Columbus, the Incan highway, being over 2,500 miles in length, was extended – meaning awfully changed as if it was extended because it was 2500 miles long.

With C, the sentence would be:
The greatest road system built in the Americas prior to the arrival of Christopher Columbus, the Incan highway, which was over 2,500 miles in length and extended from northern Ecuador through Peru to southern Chili.
The issue is the presence of and above. If this "and" was replaced by a comma, it would have been a much better sentence:
The greatest road system built in the Americas prior to the arrival of Christopher Columbus, the Incan highway, which was over 2,500 miles in length, extended from northern Ecuador through Peru to southern Chili.
Now let's look at the problem that "and" introduces, from a parallelism perspective. As you would appreciate, "and" joins two or more entities. So, since C uses and extended there must be another entity to the left of "and" that this "and" joins/is parallel with. The most logical thought would be that this "and" connects the two verbs: was and extended. In other words, the sentence is intended to be as follows:
The greatest road system built in the Americas prior to the arrival of Christopher Columbus, the Incan highway, which was over 2,500 miles in length and which extended from northern Ecuador through Peru to southern Chili.
In other words, the parallelism is between: which X (was over 2,500 miles in length) and which Y (extended from northern Ecuador through Peru to southern Chili)
The issue however is that there is no main "verb" in this sentence; in other words, there is no Independent clause. All complete sentence [u]must have at least one Independent clause.
Think about C in this way:
fozzy's car, which was old and drove fast.
- Is this a complete sentence? Clearly no. A correct sentence would have been:
fozzy's car, which was old and drove fast, met with an accident.
- Now this is a complete sentence because it has a "main verb": met. This sentence now has an Independent clause: fozzy's car met with an accident.
Similarly:
the Incan highway, which was over 2500 miles in length and extended from...
- Is this a complete sentence? Again no, because it does not have a main verb.
While most of this is more detail than you would care to know, but a holistic understanding helps in tacking SC better.
