Schedule II substances are classified as drugs that have a high potential for abuse, which can lead to severe psychological or physical dependence. They are considered dangerous but also have accepted medical uses. The examples provided in the option focused on various drugs known for their medical applications and potential for abuse.

The substances mentioned in the correct selection—morphine, cocaine, and methadone—are all recognized as Schedule II drugs. Morphine and methadone are widely used for pain management, while cocaine has certain medical uses, such as a topical anesthetic in specific procedures.
