A. of all the other planets, each contributing according to their
B. of all the other planets, with each of them contributing according to their
C. all the other planets, each of which contributing according to its

To main parallelism, we require
combined gravitational pull of the Sun and of .....

Hence C,D and E ar out.

Out of A and B, both are correct.
In B - each of them - them points to planets of the previous clause.

In A - each is directly modifying planets in previous clause .. and hence is concise.

Hence A

I don't think A is correct. From where did you get the question and the answer? I highly doubt it.

Its a 3:2 split between "of all the other planets" and "all the other planets"

We already have "of the sun" and that is not required to be repeated again.. so I would eliminate A and B straight away.
One more reason for eliminating A and B is because of the use of each (singular) and them, their (plural).. so A and B are clearly out..

E is also out based upon similar reasoning.. each and their..

Between C and D.. D is most concise..

Hence I would go for D.

i dont understand this one.
far as i know,
sun & all planets --> plural
plural + each should be followed by a plural verb. why do we have "it" instead of "their" ???

The brutal SC doc. has the answer as A but you guys are saying its D.please explan!!

IMO D.

all the other planets, each contributing according to their mass and distance from the others.

The underlined section is a modifier that modifies all the other plants.

In this phrase, each planet is the subject of the phrase. I think when we have Each as subject of phrase/sentence then we need to have singular pronoun. Hence D is correct.

Correct me, if I am wrong.
Experts help would help us on this.

Ans : a[/quote

the answer should be D instead of A
"their" in A is not good with " each" and we dont need more of
the answer is wrong 100%
