I had a hard time understanding the meaning of the sentence.

In A, it says the mantle that surrounds the core.

In D, it says the mantle the core surrounds.

Generally core means some thing at the center and mantle means some thing on the top. Rest of the choices did not make sense to me.

I ended up picking D for brevity.

What is the OA?

IMHO the sentence is not discussing core and mantle, it is concerned with "distribution of mass" within core and mantle.
A & D are out because they compare mantle with distribution of mass of core.

For someone who did not understand this sentence, D made the most sense....

going with E here is why:

whats the point of the sentence? to compare two similar mass distributions one in earth the other one in the mantle.

A - wrong comparison: mass distribution to the mantle

B - correct comparison but has a modifier problem "mantle surrounding": since "surrounding" is trying to modify "mantle" comma between the two words is needed

C – two problem: 1) same as B 2) "that" suppose to mean "like the distribution of mass" but than "of the mantle" is wrong, we are not comparing distribution of mass within the earth's core with the distribution of mass of the mantle but rather within the mantle

D - same as A (wrong comparison)

E - correct: mass distribution in the earth's core like mass distribution in the mantle has been deduced from the orbital behavior

The subject is 'distribution of the mass within the core', like what? - like 'that (distribution of the mass) within the mantle... has been deduced'

IMO :E

The distribution of mass within the core of the Earth, like the mantle that surrounds the core, has been deduced from the orbital behavior of the Earth and the motions of satellites controlled by the gravity of the Earth.
(A) the mantle that surrounds the core - APPLE ORANGE COMPARISION .
(B) that within the mantle surrounding the core-AKWARD .
(C) that of the mantle surrounding the core - REPLACE THAT WITH DISTRIBUTION OF MASS ..SENTENCE BECOMES AKWARD .
(D) the mantle the core surrounds- SEEMS SOME THING IS MISSING ..INCOMPLETE SENTENSE .
(E) the distribution of mass within the mantle that surrounds the core- CLEAR IN MEANING

E for me as well ...

like is used only for comparison ; hence , the DOM for earth should be compared to the DOM for the mantle

"The distribution of mass within the core of the Earth, like.." refers something similar to the distribution of mass... . the mantle itself can not be similar to the distribution of mass. It must be the distribution of mass of the mantle, or "that of the mantle"

B and C, I went with C, but I can see B would make a better answer.

B.
A and D are wrong coz they compare mass to mantle.
C says "that of" wheas parallelism demands "within"
between B and E, i would go with B as the comparison is intact with "like that within the mantle"..

After some thinking I am going with B.

deciding between B and E, B wins because E is wordier.

My choice is B. The comparison is b/w distribution of mass so B and E. b.w these two, E is wordy, so B wins
