So the question is now a comparison between:
A) s + (4/3)t
B) 2s + t

This line of reasoning gives the fastest solution I think. Simplify the comparison even further:
Subtract s from both sides to get
A) (4/3)t
B) s + t
Now subtract t from both sides to get
A) (1/3)t
B) s
Now the answer is clearly D since t and s can be any positive integer.
