## Why Each Wrong Option is Incorrect
- **Option A:** Without specific details on what states, we can infer that if it aligns with established facts about rugoscopy, such as its use in forensic identification or the uniqueness of rugae patterns, it would be a true statement.
- **Option B:** Similarly, if presents an accurate characteristic or application of rugoscopy, it would not be the correct answer.
- **Option C:** This option, if true, would not be the exception.
