Answer:
B
Step-by-step explanation:
When looking at the number line, we can see the distance between A and B is one unit
A |-2| + |-1| = 2+1 =3    That is not 1 unit
B 2-1  =1  that is  1 unit
C  -2 + -1 = -3  that is not 1 unit
D  |-1| - (-2) = 1 + 2 =3  that is not 1 unit 
Even though it says all expressions,  there is only 1 that shows a distance of 1 unit
