Because an oversupply of computer chips has sent prices plunging, the manufacturer has announced that it'll cut production by closing its factories for 2 days a month.

Let us closely check the options:

(A) Because an oversupply of computer chips has sent prices plunging. this is often the right option. This choice is correct as is as found out in sentence analysis.
(B) due to plunging prices for computer chips, which is because of an oversupply: the pronoun “which” refers to the plural subject “prices”. But the subsequent verb “is” is singular that doesn't agree within the number with its noun antecedent. This choice is wordy.
(C) Because computer chip prices are sent plunging, which resulted from an oversupply: 1) relevancy “which” is vague. it's not clear whether it refers to the value that was there before plunging or to the plunging price. 2) voice unnecessarily makes the selection wordy.
(D) because of plunging computer chip prices from an oversupply: 1) The events here don't seem to be presented in chronological order. The order of the events is an oversupply of chips, plunging prices, and announcements by the manufacturer. But this choice states the order as plunging prices, (due to) oversupply and announcement by the manufacturer. this modification so as creates a small amount confused on what happened first: plunging in prices or oversupply?
(E) because of an oversupply, with the result that computer chip prices are sent plunging: 1) it's better to mention, due to x, y happened instead of because of x what resulted in is y. This expression makes “with the result” redundant. 2) This choice is simply too wordy.
