I and III

x>y>z is very clear

Also y>z if, y and z are >1
if y=1/3, z=1/4 the condition is again satisfied

x>z>y is also possible

Should be 'E'.

i x =50 y =5 z=2
ii x=1/4 y=1/3 z=1/2
iii x=50 y=-5 z =2

This is one of the crazy questions, which eat you time. It took me around 3 mins to solve this.
