Since we need a solution which denotes a range between the points -7 and -2, the possible solutions are options a and d. Lets try with option a first.
In option a, we have the following inequality:

which is equivalent to

From the first inequality, we get

then we have

Similarly, from the second inequality, we have

The, the inequalty given by option a:

give us the solution

which corresponds to the given line.
Option d does not corresponds with the given line because the points -7 and -2 are not included on the inequality.. Threrefore, the answer is option a.
