A very lengthy question
Considering x as 2, following are the sets.
A - 5,3,7
B - 11,5,13
A. 7<5 No
B. 7>5 Yes
C. 7>5 Yes
D. 5>9.6 No
E. 5<9.6 Yes
F. 5=9.6 No
G.5=2*9.6 No
Hence, BCE

I don't agree that B is always true. As x gets larger, this will no longer apply.
Consider x=3
Set A = (11,7,13) and Set B = (35,19,37).
In this case, 13 is NOT greater than 19.
