Over 70 million years ago, the tectonic movements that caused the formation of the Rocky Mountains in a series of pulses during a mountain-building process known as the Laramide orogeny also resulted in the creation of the volcanic system known as the Coast Range Arc.

A. Over 70 million years ago, the tectonic movements that caused the formation of the Rocky Mountains in a series of pulses during a mountain-building process known as the Laramide orogeny also resulted

B. Caused by tectonic movements in a series of pulses, the Laramide orogeny, which is the process through which the Rocky Mountains were formed over 70 million years ago, also resulted

C. The Laramide orogeny, a mountain-building process of the Rocky Mountains, caused by tectonic movements in a series of pulses over 70 million years ago, also resulted

D. Over 70 million years ago, the tectonic movements causing the formation in a series of pulses of the Rocky Mountains during a mountain-building process known as the Laramide orogeny, also resulting

E. The Rocky Mountains, formed over 70 million years ago during the mountain-building period process known as the Laramide orogeny, caused by tectonic movements in a series of pulses, resulted

The subject of the original sentence, the tectonic movements, is modified by the following relative clause:
that caused the formation of the Rocky Mountains in a series of pulses during a mountain-building period process known as the Laramide orogeny
After verifying there are no mistakes in this relative clause, we may ignore it. The rest of the sentence is still correct:
... the tectonic movements ... also resulted in the creation of the volcanic system known as the Coast Range Arc.

A for me.

BCE each changes the meaning.

D: the -ing form does not sound very well.

I cross off BCD and leave AE
the reason that I cross E off is we don't know what "caused by tectonic movements in a series of pulses" modifies either The Rocky Mountains or Laramide orogeny.

I think the meaning approach is very useful to answer this question. there is no clear grammatical error to eliminate options. please experts help me if I am wrong.

Over 70 million years ago, the tectonic movements that caused the formation of the Rocky Mountains in a series of pulses during a mountain-building process known as the Laramide orogeny also resulted in the creation of the volcanic system known as the Coast Range Arc.

A. Over 70 million years ago, the tectonic movements that caused the formation of the Rocky Mountains in a series of pulses during a mountain-building process known as the Laramide orogeny also resulted >> perfect

B. Caused by tectonic movements in a series of pulses, the Laramide orogeny, which is the process through which the Rocky Mountains were formed over 70 million years ago, also resulted >> Not the subject, second red part (IMO) is awkward, and makes passive

C. The Laramide orogeny, a mountain-building process of the Rocky Mountains, caused by tectonic movements in a series of pulses over 70 million years ago, also resulted >>Not the subject

D. Over 70 million years ago, the tectonic movements causing the formation in a series of pulses of the Rocky Mountains during a mountain-building process known as the Laramide orogeny, also resulting >> Run-on sentence, no verb
E. The Rocky Mountains, formed over 70 million years ago during the mountain-building period process known as the Laramide orogeny, caused by tectonic movements in a series of pulses, resulted >> Not the subject

A is the right answer. B, C, and E all change the meaning of the sentence. D is awkwardly phrased, ‘causing the formation seems odd’.
