Good solution! Especially pointing out that red herring.
I think you don't have to worry about the most in this argument, you could write it as: most criticism --> devoted to art work not satisfy them.
Below yours, I've put a bit more intuitive approach, along with a discussion of the wrong answers.

Criticism -most→ devote to art work not satisfy them
----------------------------------------------------
Criticism -most→ devote to work that are not greatest work
Criticism -most→ devote to art work not satisfy them
→ devote to work that are not greatest work
Contrapositive:
(E)Greatest art work →satisfy criticism
A -most→ B
-------------
A -most→ C
Missing assumption: A -most→B→C
The conclusion of this argument is that most art criticism is devoted to art that is not the greatest. Why? Because most art criticism is devoted to art that fails to satisfy the critics.
What's the gap? Well, who says that the art that fails to satisfy the critics is not the greatest. Maybe the greatest is all about which art is sold for the most money.
(E) fills the gap, telling us that the greatest works of art ALWAYS DO satisfy the critics, thus (here comes the contrapositive), if the critics are not satisfied, the work is not the greatest.
(A) is out of scope - it's about what the critics enjoy writing.
(B) is also out of scope. Discovering art?
(C) is also out of scope! We don't care about attention to art.
(D) is, you guessed it, out of scope. We're not interested in art getting recognized.
