The vertical bars stand for absolute value
Whenever you take the absolute value any number, it will always result in a positive number.
So in other words, if we evaluate we will get 12. Likewise if we evaluate we will get 12 also. If and we evaluate then as a result. So basically any negative number loses its sign and becomes positive.
So this property can be described through this inequality:
Since our problem becomes:
-2______2 <---------Notice I replaced with
Now we can see that -2 is less than 2, so our answer is
So the answer is B)

---------------------------
Strictly speaking |-------| means "distance"
Example:
|2 -3| means the distance between 2 and 3 which is 1
|-2| means |-2-0| which is the distance from -2 to 0 which is 2
-------------------
Your problem:
-2______|-2| is the same as saying
-2______ 2
The answer is <
-2 < |-2|
