OA A, not able to make the problem with D

Dear AnjaliOberoi,
I'm happy to respond.

The problem with (D) & (E) is the phrase "due to." The phrase "due to" is not entirely synonymous with "because of", but it is often erroneously used this way. The words "because of" are a compound preposition, so "because of X" can be an adverbial phrase that modifies the action of the following clause. By contrast, the word "due" is an adjective, and needs to modify a noun. When the phrase "Due to A" begins a sentence, the first noun following that phrase is modified by "due". Think of the sentence in (D):
Due to plunging computer chip prices from an oversupply, the manufacturer has announced that it will cut production by closing its factories for two days a month.
In that version, we are saying that the "manufacturer" is "due to plunging computer chip prices ...." --- in other words, the manufacturer is somehow caused by plunging prices ---- of course, that makes no sense at all.

Does this make sense?
