I thought "solely" is required, else it changes the meaning... but I am wrong.

(A) all layers of the earth are contained solely
(B) all layers of the earth are contained
(C) all layers of the earth is contained solely
(D) all layers of the earth is contained
(E) many layers of the earth is contained

Since the passage already says "all the water contained", "solely" is considered redundant and unnecessary. Therefore the answer is D.

(A) all layers of the earth are contained solely
Wrong. "all of the water" is singular --> "are" is wrong.

(B) all layers of the earth are contained
Wrong. Same as A. "are" is wrong.

(C) all layers of the earth is contained solely
Wrong. "solely is redundant because of the phrase "all of the water".
For example:
- Because of an accident, all drivers used solely freeway 101 <-- "solely" modifies "freeway 101". However, "ALL driver used freeway 101" means NO drivers used other freeways. Thus, freeway 101 was the only choice for drivers. --> we don't need solely/only here.

Back to the question.
"all water contained in all layers" also indicates there is no water contained in other layers. "the surface" is the only choice for water to contain. We don't need "solely" anymore.

(D) all layers of the earth is contained
Correct.

(E) many layers of the earth is contained
Wrong. "many layers" is totally different from "all layers".

Hope it helps.

Echo the same as a few above--the sentence states "all the water"--so, we don't need to clarify by using the word "solely" to determine how much of the water we're talking about.

All choices with "are" are wrong as we have a singular subject, requiring "is".

I did not get it.
I think 'all drivers used solely freeway 101' and 'all driver[sic] used freeway 101' both mean the same - No drivers used any other freeway.
What am I doing wrong?
Also, isn't the sentence a little absurd because it uses 'contained' twice?
All of the water contained in all layers of the earth is contained solely in the earth’s surface area.
I'm also confused with the tense - No hydrogen was retained in the interior; therefore water is contained in the earth's surface area

It is too much to say "solely" is redundant in this sentence.
