hi Aditya,

Can you please re-check your first option? I find discrepancy in the original statement and the option A you have provided.
I'm no expert, just trying to work on my skills. If I've made any mistakes please bear with me.

The fight is between C and D.

The Adirondack mountains ...are in the shape of a dome , "because of" should be used to describe this verb and therefore C

I chose D. In C, I thought 'occuring' can't be used for a past event. Substituting 'due to' with 'caused by', in D, didn't sound wrong to me.

Any thoughts on this ? Am I wrong ?

well it is indeed wrong

this is not correct .though i had rejected C for some other reason. in C usage of two modifiers back to back seems awkward !!

Elimination:
A: largely in due sounds awkward and changes the meaning of the sentence.
B: it says tht the crust itself gets lifted, whereas under the crust d
Shld get lifted
E,C: occurring- tense change .....which shows tht its happening , which is not true.

So I choose D.

I chose C. It sounded better than D to me although occuring at the end does not sound very perfect.

what's the OA?

Ignore this SC.

In C, occurring cannot serve to modify uplift, a noun in the preceding prepositional phrase.
On the GMAT, a COMMA+ VERBing modifer such as occurring must serve to modify the SUBJECT AND VERB of the preceding clause.
Here is C, with the intervening modifiers omitted:
The Adirondack mountains are in the shape of a dome, occurring about a billion years ago.
The implication of this structure is that occurring about a billion years ago refers to the ADIRONDACK MOUNTAINS.
Not the intended meaning.

One more thing:
Because COMMA+VERBing serves to modify -- at least in part -- the preceding verb, it takes on the TENSE of the preceding verb.
In C, the preceding verb is are.
Since are is in the present tense, occurring must also be taking place in the present.
The result is a contradiction in terms: that something is occurring -- RIGHT NOW -- about a billion years ago.
