Answer: A 
F14.282 is appropriate for this case because it is used for cocaine dependence with a cocaine-induced sleep disorder which is seen in the patient. 
Option B is not correct because F14.281 codes for cocaine dependence with cocaine-induced sexual dysfunction. 
Option C is not correct because F14.280 codes for cocaine dependence with a cocaine-induced anxiety disorder. 
Option D is not correct because F14.99 codes for cocaine dependence with the unspecified cocaine-induced disorder.
