Why E is better than C?

In A, due to seems to modify the automobile industry, implying that the INDUSTRY was due to JOBS -- a nonsensical meaning.
Eliminate A.

In B, one (singular subject) does not agree with were (plural).
Eliminate B.

In D, when seems to refer to the economy. When must refer to a MOMENT IN TIME.
Also, the past perfect must refer to an INDEFINITE moment in the past. Thus, it is incorrect to say that the industry had dominated IN THE 1920's.
Eliminate D.

HAVING + past participle implies an action that took place PRIOR to the main verb.
Thus in C, having been employed implies that the workers were employed BEFORE the industry dominated.
Not the intended meaning.
The intended meaning is that the two actions happened AT THE SAME TIME.
Eliminate C.

The correct answer is E.

having done
can used before or after a main clause to modify the clause/main verb. we need comma to separate "having done phrase" from main clause.

NOUN HAVING DONE dose not exist in general grammar and so in gmat grammar. eliminate this pattern without thinking because this is mechanical grammar error.

NOUN DOING show

noun which will do
noun which did
noun which had done
.......
any tense. that is why "doing" in this case is call verbal, "no time".
