Sentence Correction

....

IMO C:

The army .... is more than 2000 years old and took 700000 artisans more than 36 year to complete.

Since army is singular, A is wrong, it in B though correct, distorts the parallelism, see abobe, the army is..and tokk...it?

E is again using them so wrong. D is wrong as it breaks required construction with the army as Subject

i would also go with C because in A "them" is not correct..........wats the OA????

I would like to have a clear understanding on the below bolded portion

...the army of terra-cotta warriors created to protect QSH,China's first emperor, in his afterlife is more than 2000 years old...

As per my understanding,
China's first emperor = appositive = this is okay with me
but,
created to protect QSH in his afterlife = is this a modifier? what sort of modifier is this?

IMO B

X Building took 50000 warriors 25 years to complete OR
X Building took 50000 warriors 25 years to complete it

Second sounds right..experts please


Whats the OA

p.s :

IMO C

Rivaling the pyramids of Egypt or even the ancient cities of the Maya as an achievement, the army of terra-cotta warriors created to protect Qin Shi Huang, [spoiler]China's first emperor[/spoiler], in his afterlife IS more than 2,000 years old and TOOK 700,000 artisans more than 36 years to complete.

What's the OA?

Edit: the OA is [spoiler]"C"[/spoiler] -> https://www.manhattangmat.com/forums/gmatprep-t6880.html

A parallel example, made more brief:

My commute is two miles long and took me half an hour this morning. The parallelism is in the verbs, as MAAJ pointed out!
