This one is inherently about meaning and I myself, admittedly, missed the error in B (and elsewhere)
Although she was considered among her contemporaries to be the better poet than her husband, later Elizabeth Barrett Browning was overshadowed by his success.
(A) Although she was considered among her contemporaries to be the better poet than her husband,
later Elizabeth Barrett Browning was overshadowed by his success.X
There are two errors here. The first error is that the subordinate clause starting with 'although' is followed up by 'later' after the comma. Browning should follow the comma. Error #2 is the sentence conveys that Barrett herself was overshadowed by her husband's success when it should be the case that her success was overshadowed by his (success).
(B) Although Elizabeth Barrett Browning was considered among her contemporaries as a better poet than her husband,
she was later overshadowed by his success.
Tthe sentence conveys that Barrett herself was overshadowed by her husband's success when it should be the case that her success was overshadowed by his (success).
(C) Later overshadowed by the success of her husband,
Elizabeth Barrett Browning's poetry had been considered among her contemporaries to be better than that of her husband.
This suffers from a modification errior.
(D) Although Elizabeth Barrett Browning's success was later overshadowed by that of her husband, among her contemporaries she was considered the better poet.
Correct
(E) Elizabeth Barrett Browning's poetry was considered among her contemporaries
as better than her husband, but her success was later overshadowed by his. X
Browning's poetry cannot be considered than a human being.
