Answer:

A

Step-by-step explanation:

| x-6| = 15 , check if this is true for the given x values

for x= -9 we have | -9-6| =  15 true

for x= 21 we have | 21 -6| = 15 true

so A is a solution set

for x= -15 we have | -15-6| =  15 false

so B is not a solution set

for x= 9 we have | 9-6| =  15 false

so C is not a solution set

for x= -9 we have | -9-6| =  15 true

for x= -21 we have | -21-6| =  15 false

so D is not a solution set

for x= -6 we have | -6-6| =  15 false

so E is not a solution set
