(A) himself a reformed alcoholic, traveled repeatedly to the Indiana territory to unite

(C) a reformed alcoholic himself, traveled repeatedly to the Indiana territory for uniting
(D) himself as a reformed alcoholic, traveled repeatedly to the Indiana territory so as to be the uniter of
(E) who had been himself as a reformed alcoholic, traveled repeatedly to the Indiana territory for the uniting of
Solution: The original underlined phrase looks grammatically correct as it has the proper use of 'to unite' and the noun modifier phrase. Let's look at other options also.
(A) himself a reformed alcoholic, traveled repeatedly to the Indiana territory to unite
Explanation: As discussed above, let's keep this.(B) being a reformed alcoholic himself, traveled repeatedly to the Indiana territory so as to unite
Explanation: Here 'so as to unite' is very wordy and so is the use of 'being a reformed alcoholic himself'.
INCORRECT(C) a reformed alcoholic himself, traveled repeatedly to the Indiana territory for uniting
Explanation: Here 'using himself' after reformed alcoholic is redundant. Also 'for uniting' is wrongly used, 'to unite' is the proper usage.
INCORRECT(D) himself as a reformed alcoholic, traveled repeatedly to the Indiana territory so as to be the uniter of
Explanation: Awkward and wordy usage of words here. 'So as to be the uniter of' changes the intended meaning of original sentence. Also 'himself as a' is redundant.
INCORRECT(E) who had been himself as a reformed alcoholic, traveled repeatedly to the Indiana territory for the uniting of
Explanation: Similar problems of awkward and wordy usage of words here as well. 'for the uniting' is wrong. Also the modifier phrase before comma is wordy and redundant.
INCORRECTHence,
Option A is the right choice.
