We try each one:
Try A
Cross multiply:
No that's false, so A isn't the answer.
Try B
Cross multiply:
That's true, so B is the correct answer. But let's go though the
others anyway to show that they are not the correct answer:
Try C
Cross multiply:
No that's false, so C isn't the answer.
Try D
Cross multiply:
No that's false, so D isn't the answer.
The correct answer is B
