Correct the sentence

Today I came across this multiple-choice question,
"----- Frances Perkins held the post of labor secretary for twelve years.
(A) The first woman appointed by a United States President to a cabinet position was
(B) The first woman appointed by a United States President to a cabinet position
(C) Appointed by a United States President to a cabinet position was the first woman who
(D) The first woman was appointed by a United States President to a cabinet position who"

The answer they give me is B. I am confused. I know that the other three are wrong. But don't you think we miss an 'as', if we choose B?
" As the first woman appointed by a United States President to a cabinet position, Frances Perkins held the post of labor secretary for twelve years."

Or we can just change held to holding , then A) will work.
:-s

B works if you add a pair of commas.



The first woman appointed by a United States President to a cabinet position, Frances Perkins, held the post of labor secretary for twelve years.

I do think your version of it is better, if that eases your confusion.

Yes, it does. It does ease my confusion and worries. Actually, this question appeared in one TOEFL test. I guess typos might happen during copying, though, I still don't know the exact one.

But That's Ok, as long as I know what's going on.

As for adding a pair of commas, I don't think that sentence would be strong, I mean strongly organized, thought it's grammatically correct.

A book on statistical methods in the social sciences and several essays are required reading in the next course.
