Answer 1

D) birds overcome by pollution routinely fell from the sky above Los Angeles freeways, prompting officials in California to devise a plan to reduce

Step-by-step explanation:

In option A, the use of 'and/this' is wrong. In addition, the use of 'since/prompted' is also wrong.

In option B, the use of 'had been overcome' is wrong. It also contains a similar redundancy error to option A.

In option C, there are verb tense and reduced errors as in options A and B

In option D, there is no error.

In option E, there is disorganization of the actual meaning of the sentence.
