I agree that this was quite a challenging question but there were a few clues in the question.

The first clue is the use of the word "ban" itself- To ban means to prohibit or to put a stop to something legally. To ban salary cap is illogical. The Removal of the salary cap is appropriate. 
In addition to the removal of the salary cap, their demands include- 
What do their demands include? a stratification system based on statistical performance? 
No. Their demand is that it should be implemented. The command subjunctive is to be used in the sentence.

E over A for logical clarity, correct use of command subjunctive, and maintains parallel structure.
