Morphine is the natural opiate derived from opium and the prototype opioid analgesic. It is a full agonist at mu opioid receptors, producing potent pain relief and the classic opioid effects. In the list, one item is literally Morphine—the natural opiate. The others are different classes: levorphanol is a fully synthetic opioid with similar activity; oxycodone is a semi-synthetic opioid; nabilone is a synthetic cannabinoid, not an opioid. Since the question asks which drug is Morphine, the correct choice is the one that is the actual natural opiate, Morphine.
