Observe that all the equations are the same.
Also note that all the lines are solid. This should tell you that the inequities should involve.

Therefore the answer is between option A and B.
So we choose a point in the solution region to discriminate between A and B.

We substitute into option A to get.



The above statements are false
We now substitute into option B



Both statements are true, therefore the correct answer is option B.
