Solution
D. I, II, and III
Explanation:
I. Neurochemical changes in the brain: Physical drug dependence often involves changes in the brain's neurochemistry. The brain adapts to the presence of the drug and may function abnormally without it.
II. Withdrawal symptoms with cessation of drug use: When a person stops using a drug upon which they have become dependent, they may experience withdrawal symptoms. This is a clear sign of physical dependence.
III. Tolerance to the drug used: Tolerance is a common aspect of physical drug dependence. Over time, a person may need to use more of the drug to achieve the same effect, indicating that their body has become accustomed to the drug.
