Let's go through each answer choice one at a time.
--------------------------------------------------
Choice A
3/4 < 5/7 
3*7 < 4*5 ... cross multiply
21 < 20
The last inequality is false, so the original inequality is false
Choice A is false
--------------------------------------------------
Choice B
2/3 > 5/6
2*6 > 3*5 ... cross multiply
12 > 15
The last inequality is false, so the original inequality is false
Choice B is false
--------------------------------------------------
Choice C
5/8 > 6/10
5*10 > 8*6  ... cross multiply
50 > 48
The last inequality is true, so the original inequality is true
Choice C is true
--------------------------------------------------
Choice D
4/5 < 2/9
4*9 < 5*2  ... cross multiply
36 < 10
The last inequality is false, so the original inequality is false
Choice D is false
--------------------------------------------------
In summary, we have
