Answer:
Option B: x > 0
Step-by-step explanation:
Option A is wrong because
will be 0. So, the inequality can't be divided by 0.
Option C is wrong because 1 will suffice this inequality. 
Option D is wrong because any value in the root has to be greater or equal to 0 (otherwise, it's imaginary number). -1 will give the latter root a value of root-(-3).
Leaving us with only option B, which is the right answer.
77, 80, 87, 88, 92, 94, 99
the median is 88
Q1 is 80 and Q3 is 94
94-80 = 14 which is the interquartile range
therefore, your answer is D) 14
