To me, both E and D are potential candidates. However I would reject D for below reason-

from right handers' does not clear out the comparison between patterns whereas in E, use of a "from that of" makes the comparison clear.

question compares the pattern of BO of left handers and right handers, use of word "that" conveys that the BO is different but we need the patterns. hence its wrong.

Hi,
To know why D is wrong lets discuss a bit about pronoun ambiguity. A pronoun is a word that replaces a noun...means any noun (but has to follow the same number as of noun). A pronoun can refer to any noun i.e nouns in different clause , noun in prepositional phrase , noun preceding to pronoun , noun after the pronoun...e.t.c. To check right pronoun we put all the possible noun in place of that pronoun and think which noun is logically fit. If one noun is logically fit with grammatically correct then the pronoun refers to that particular noun. If more than 1 noun are logically fit then we say there is pronoun ambiguity. And if there is not a single noun to which pronoun refers logically then its missing the antecedent and hence makes grammatically wrong.

Now lets discuss a bit about 'that'. 'that' is a pronoun that could act as a connector between two clause or could act as a subject, which is basically a pronoun, for the followed clause. 'that' is a relative pronoun that refers to preceding noun and may refer a bit far away noun as well if that noun is modified with prepositional phrase.

In this option D..'that' word is not acting as a connector between two clause rather it is acting as a subject of the clause " is quite different ......'. Here, since 'that' is acting as a subject (means as a pronoun), 'that' must refer to a preceding noun. The preceding noun could be either 'brain organization' or 'a pattern'. Because 'a pattern' is modified by prepositional phrase 'of brain organization' , 'that' could refer to 'a pattern'. Now to check which makes logically sound read the option by replacing 'that' with both the noun.
Lets check for 'a pattern'...then it would be ...----a pattern is quite different from right-handers' ----. Makes logically sound.
Now, lets check for 'brain organization'.....----- brain organization is quite different from right-handers' ------ Makes logically sound.

As we have seen that 'that' has two logically sounded noun, it confuses and makes pronoun ambiguity error. Thus, this option is incorrect due to pronoun ambiguity error.

+1 kudos if it helped you

It may be noted that the relative pronoun 'that' is 99% used as a restrictive pronoun that modifies the noun that is just in front. Here the noun is the organization. The pronoun ' that' does refer to the organization. So there is no ambiguity about what 'that' refers to. It is this unambiguity about the 'that', which is the undoing of choice D, because we don’t need ‘that’ to refer to organization but to a pattern and hence D is clearly out.
E, on the other hand, prudently avoids the restrictive ‘that’ and is clearly one-up over D.
