A) correct.
B) incorrect. "have typically see"
C) incorrect. "have been seeing"
D) incorrect. "have been able to"
E) incorrect. "marking by" implies visitors are doing the marking.

I went with A, but D looks tempting as well. Anyone know why it's wrong?

"been able to see" is wordier than seen.
Also, you need that (as used in A) to demonstrate that the colors mark the passage of time.

D for me.

This is a classic case of gerund usage. The "colors" clause should modify the first clause of "seeing canyon".

Therefore the colors clause should be a subordinate clause of the first clause.

Therefore only D fulfills that.

A seems to indicate that people are seeing canyons ALONG with different colors.

Setence has pronoun and modifier issue.
(A) seen layers of sediment in the gaping canyon, with different colors that mark
(B) see layers of sediment in the gaping canyon, whose different colors mark [Whose - can point to layers of sediment or gaping canyon - eliminate it]

(C) been seeing layers of sediment in the gaping canyon, whose different colors are markers of [Whose - can point to layers of sediment or gaping canyon - eliminate it]
(D) been able to see layers of sediment in the gaping canyon, with different colors marking [ been able to see - compare to A - verbose ]
(E) seen layers of sediment in the gaping canyon, marking by different colors [Not sure which one that Marking modifies - can point to layers of sediment or gaping canyon - eliminate it

Answer: A

my first guess was D

A is quite close as well , but i was less inclined towards A as the words "that mark" look a bit suspicious .It appeared as if grand canyon is being
refrd by "that"

Yeh its true that "been able to" is wordy but still if it conveys the meaning more correctly , then it shud be the choice

I thought D since it seemed to follow the parallelism structure better than A(though A sounds good too, I chose D for the parallelism). I dont see what is wrong with "have typically been able to see".

I see. I can agree with this one.

Those who have visited the Grand Canyon have typically seen layers of sediment in the gaping canyon, with different colors that mark the passage of time like the rings in a tree trunk.

It's not the different colors that mark the passage of time like the rings in a tree trunk, but rather the layers of sediment.

Using that mark here is incorrect as it should be referring to layers of sediment, not the colors.
