Explanation

Creating a filter: in the underlined portion of the original sentence, the pronoun "those" is suspicious, because it's a pronoun. However, the pronoun refers clearly to "changes." So the original sentence may not be defective. We'll proceed to (B).

Finding objective defects: in (B), "with" is not properly a conjunction, and it's not being used to convey its actual meaning, as in "along with." So (B) is out, as is (E), which also makes the "with" mistake. Choice (C) introduces a new pronoun, "it," appearing to destroy the intended meaning of the sentence, which in that case doesn't mention the market anymore. Choice (D) has a pronoun issue: "them" should be "it," to refer to the singular "supply chain." Choice (D) is out. We are down to one. The correct answer is (A).
