Official Explanation:
The underlined portion of the sentence contains the pronoun they, so check that it agrees with a specific plural noun in the sentence. The underlined portion also contains the adjective less, so check that it is used in reference to a non-countable noun. The plural pronoun they incorrectly refers to the singular noun company, which is a pronoun agreement error. Because less refers to the countable noun bricks, this is a quantity words error. The correct word is fewer. Eliminate choice A for both the pronoun agreement and quantity words errors and look for any obvious repeaters. Choice B is an obvious repeater of both errors because it also contains the plural pronoun they and the quantity word less. Eliminate choice B. Choice D is an obvious repeater of the pronoun agreement error because it also contains the plural pronoun they. Eliminate choice D. Now, evaluate the remaining answer choices individually, looking for reasons to eliminate each.
Choice C contains the phrase, used the realization of, which changes the meaning of the sentence, so eliminate choice C. Choice E fixes the original pronoun agreement error by replacing they with it, fixes the original quantity word error by replacing less with fewer, and introduces no new errors, so keep choice E.
Alternatively, if it is difficult to spot which grammar rule the sentence is testing, another strategy is to try to identify an error from the answers by looking for either a 2/3 split or differences among the answers. Since three answer choices use the plural pronoun they and the others use the singular pronoun it, this difference is an indication to look for agreement errors. Furthermore, since three answer choices use the quantity word fewer, and the others use less, this difference is an indication to look for quantity word errors.
