Because of wireless service costs plummeting in the last year,and as mobile phones are increasingly common,many people now using their mobile phones to make call across a wide region at night and on weekends,when numerous wireless companies provide unlimited airtime for a relatively small monthly fee.

(A)Because of wireless service costs plummeting in the last year,and as mobile phones are increasingly common,many people
(B)As the cost of wireless service plummeted in the last year,and as mobile phones became increasingly common,many people
(C)In the last year,with the cost of wireless service plummeting,and mobile phones have become increasingly common,there are many people
(D)With the cost of wireless service plummeting in the last year and mobile phones becoming increasingly common,many people are
While the cost of wireless service has plummeted in the last year and mobile phones are increasingly common,many people are

Plummeting costs should not encourage people to increase their cell phone usage during the hours with unlimited airtime, so the second clause doesn't follow from the first without a subordinating conjunction of contrast such as while, whereas, or although.

I would go with choice E, because it's the only answer choice that introduces this contrast between the clauses. OA?

I would go with D.

I discarded E for bad parallelism. Think of the meaning of the sentence. 'While' introduces two events that occur at the same time- therefore, the tense of the of 'plummeting cost' and 'the usage of mobile phones' should be the same. On the contrary, E introduces "has plummeted" and "are common".

Hope this helps.

IMO D.
In E, the verb tense is not consistent. The plumeting of cost and increased use of mobile phones should use consistent tense.

I am not an expert. If I am wrong, I would really apreciate if someone corrects me.

I would go with D.
A: "Because of" & "As" do not parallel. Fragment: "Many people" should be followed by a verb "are"
B:Fragment
C:bad parallelism. "There are many people", here "there be" means something naturally exists. In this sentence it makes no sense.
D:correct
E:bad parallelism.

I hope the explanation helps.
