With a painting style built on abstract shapes and Eastern techniques, she was by far the most unique student at the entire academy.
As per my understanding:
A. she was by far the most unique student at the entire academy. - wrong
Error Analysis :
" Unique" it self is unique word , which does not need most or more to it . It will be redundant.
best in the academy itself conveys the meaning that best in the entire academy , here entire will be redundant.
B. she was by far the most unique student of the ones at the academy. - redundant
(Most and Unique) and also says one among most unique ones which is wrong . Unique is only 1 .
C. she was the most unique student by far at the entire academy. -redundant ( Most - unique)
D. she was by far the most unique student among the entire academy.-redundant , also among the entire
academy -- students
E. she was unique among all of the students at the academy.-Correct Kudos , please ………………..
