Answer:
A.
Explanation:
since we are using the absolute value this means the result to be between 0 and 3.
the difference to C. is that the endpoints are not included (empty dots). that is correct, because the inequality uses the "<" sign. being equal to 3 is not valid.
but any real number higher than 2 and lower than 8 will provide a valid solution.
the higher or lower numbers used in B. and D. will not create anything between 0 and 3.
