First step while solving any SC question should be to determine the flaws in the question statement, if any. Let's do just that.
Uranus's atmosphere should be compared with Jupiter's atmosphere. However, per this sentence, Uranus's atmosphere is compared with "that of Jupiter's atmosphere". This clearly does not make sense. Thus, the first error the question statement suffers from is parallelism. The two entities compared should be similar to each other. Also, the usage of "in that" to denote how these two entities are similar is not quite approporaite. Let's try to find an answer choice that does away with 'in that'.
(B) The parallelism error of (A) is repeated here. Atmosphere of Uranus is compared with that of Jupiter's. Also, the verb "in it's being" is very problematic. Just not what you would see on a correct GMAT SC question. Eliminate (B) on the basis of these two problems.
(C) Atmosphere of Uranus and Jupiter are not comparable entities. One can either compare Uranus and Jupiter or the atmospheres of the two planets. This choice is incorrect because of parallelism error. Also, has this choice been something like : "The atmosphere of Uranus is full of hydrogen and helium just as atmosphere of Jupiter [i]has". This sentence would've been incorrect because of the verb error. Has should be replaced with is.
(D) Again, uranus's atmpsphere is compared with that of Jupiter's. -- INCORRECT. Also, we should employ 'like' instead of 'as' because when used for cmparing two entities, 'as' must be followed by a clause (unless ellipsis is at play).
(E) This is the correct choice as it corrects the parallelism error of (A). Like is used appropriately here. 'in that' is also removed from the sentence. This option expresses the meaning coherently while employing correct grammar.
