This one is tricky.
First, there is nothing grammatically wrong with the example sentence as it stands. It's simply a dependent prepositional phrase and then the main sentence. In fact, you can easily reverse the sentence and see this:
Because an oversupply of computer chips has sent prices plunging, the manufacturer has announced that it will cut production by closing its factories for two days a month.
OR
The manufacturer has announced that it will cut production by closing its factories for two days a month because an oversupply of computer chips has sent prices plunging.
Either one works, which shows that it is grammatically correct. Choice D
changes the meaning of the sentence. In the main sentence the factory production is cut because of an oversupply of chips, but in choice D the factory closed down from plunging prices. Therefore A is correct.
Hope this helps!
