Answer

A

Explanation

All numbers are positive.

In the upper left, \text{y} is bigger than \text{x}. \dfrac{\text{b}}{\text{a}}>1.

In the lower right, \text{x} is bigger than \text{y}. \dfrac{\text{d}}{\text{c}}<1.

So \dfrac{\text{b}}{\text{a}}-\dfrac{\text{d}}{\text{c}} is always positive. The answer is A.

In the upper left, \text{y} is bigger than \text{x}. \dfrac{\text{b}}{\text{a}}>1.

In the lower right, \text{x} is bigger than \text{y}. \dfrac{\text{d}}{\text{c}}<1.

So \dfrac{\text{b}}{\text{a}}-\dfrac{\text{d}}{\text{c}} is always positive. The answer is A.
