Final answer:
The answer is True. For cross-dressing to be classified as transvestic disorder according to DSM-5, it must cause the individual significant distress or dysfunction, irrespective of frequency or level of arousal.
Step-by-step explanation:
The question is asking whether an individual who engages in cross-dressing for sexual arousal and experiences distress from this behavior would be considered to have transvestic disorder. According to the DSM-5, for a behavior like cross-dressing to be classified as a disorder, such as transvestic disorder, it must cause significant distress or dysfunction to the individual, regardless of how often the cross-dressing occurs or how sexually arousing it is found to be. Therefore, the answer to the question is A. True. If the cross-dressing does not cause distress, it would not be considered a mental health disorder.
