Good question, beattheheat!

Clearly except for A, all others are ungrammatical and wordy.
B - by means of regions is ungrammatical and usage of which is incorrect.
C - usage of "as such" is wordy and facilitating is wrongly used without parallelism and correct tense.
D - unnecessary usage of being and wordy
E - usage of which is incorrect

A seems to be the best among the given choices however that is a singular pronoun and the verbs used "identify" and "facilitate" are plural. Is that correct? Any expert opinion will be appreciated.

Hi, beattheheat, I do have similar confusion. That always follows touch rule and in the sentence it seems to modify the intestine wall. In such a case, verbs don't agree in number with singular noun wall. mikemcgarry Can you pls help here.

Thanks

"facilitating..." will have to be an action that results from the previous clause. However, since the preceding clause contains "and", it is illogical to have "facilitating" here.
Also, "as such" is wordy.

C is wrong.

Hi Experts,

Can you please clear the doubt here. As per A "that" refers to wall which is singular and the verbs include and facilitate are plural. Also , as per the meaning it should be the regions which "include" "facilitate" and hence the plural verbs would make sense. Just because of 'that' , I rejected option A and chose C.

umrani.sonali The modifier "that identify antigens . . . " applies to "regions," not "wall." Normally a noun modifier applies to the adjoining noun. However, in this case, the entire stretch from "regions" to "wall" is one big noun phrase: regions (of lymphatic tissue) (in the intestinal wall). Since those modifiers are "mission-critical" for specifying what regions we're talking about, we can skip over them in applying the modifier. If we read "that" as modifying "wall," the sentence doesn't make sense. This implies that there is one intestinal wall that identifies antigens and another that does not. Also, there is no answer choice that successfully conveys that meaning, so we can rule it out.

a. are regions of lymphatic tissue in the intestinal wall that identify antigens within the intestine and facilitate (Correct)
b. by means of regions of lymphatic tissue in the intestinal wall which identify antigens within the intestine, facilitating (Lack of main verb in the sentence)
c. are regions of lymphatic tissue in the intestinal wall and, as such, are identifiers of antigens within the intestine, facilitating (Patches are identifiers of antigens. It totally changes the meaning)
d. being regions of lymphatic tissue in the intestinal wall, identifying antigens within the intestine, and facilitating (Same as B)
e. regions of lymphatic tissue in the intestinal wall which identify antigens within the intestine and are facilitating (Same as B)
