Here, the correct idiom is 'admiration for' and not 'admiration of'. Therefore, options D and E do not fit the context. Since, the sentence is one of contrast - between Tagore's admiration for Gandhi and his skepticism regarding Gandhi's form of nationalism and opinions, the 'not only ... but also' structure is incorrect as it is used for affirming something and not contrasting. Thus, option C too doesn't fit the context. Now, the sentence requires a parallel structure- the use of '...and also...' in A does not fit a parallel structure whereas '...as...as...' in B does support a parallel structure. Therefore B is the correct answer.
