Answer:
A) X<0
Explanation:
x is not greater than zero, so the last two options can be crossed out.
Now A & B are left. Since 0 has an open circle, it means 0 is not a value of x, therefore it has no line under the inequality sign. If 0 was a closed(shaded) circle, B would be the correct answer because X could have a value of 0.
