distinguish 也有 distinguish A from B 的用法

A former director of the Central Intelligence Agency has said that the surveillance capabilities of United States satellites would enable a skilled photographic interpreter to distinguish(between Guernsey and Hereford cows grazing) in a meadow.
A.between Guernsey and Hereford cows grazing
B.between Guernseys and Hereford cows that graze
E. Guernsey from Hereford cows grazing
why the answer is A?为什么E 不对？distinguish 也有 distinguish A from B 的用法

此题可以这样考虑,因为distinguish A from B 要求两者间具有同质性,可是Hereford cows grazing in a meadow中的Hereford cows 有定语,而前面的Guernsey 没定语,违反了平行结构的要求.
