Three out of every four automobile owners in the United States also own a bicycle. (A) Three out of every four automobile owners in the United States also own a bicycle. -- Correct
(B) Out of every four, three automobile owners in the United States also owns a bicycle. -- subject -verb agreement --three owners owns
(C) Bicycles are owned by three out of every four owners of automobiles in the United States. -- it becomes a statement about bicycles, and thus takes on an unreasonable meaning.
(D) In the United States, three out of every four automobile owners owns bicycles. -- subject -verb agreement -- three owns
(E) Out of every four owners of automobiles in the United States, bicycles are also owned by three. -- the phrase beginning Out of every four ... cannot properly modify bicycles, and the passive construction (bicycles are also owned) is awkward and does not contribute meaningfully to the sentence. The plural nouns bicycles and automobiles suggest imprecisely that each person owns more than one of each.

Teenage girls are concerned with fashion.
2/
Fashion is a concern of teenage girls.
The first statement is about teenage girls. I.e., according to #1, teenage girls in general are concerned with fashion, i.e., it's relatively rare to find a teenage girl who is unconcerned with fashion.
#1 says nothing about whether other demographics (e.g., teenage boys, middle-aged adults) are concerned with fashion.
The second statement is about fashion. According to #2, fashion is largely confined to teenage girls, and it's rare to find someone else (a boy or an adult) who is concerned with fashion.
#2 says nothing about whether most teenage girls are concerned with fashion.
Note the wide divergence between the two. In fact, #1 is basically true while #2 is false.
That's the problem with C: it implies that the ownership of bicycles is largely confined to people who also own cars. Weird.
(You can also eliminate it because it's needlessly indirect, but that's the real reason.)
