Final answer:
One sign of an addict is craving another drink. Another sign is being willing to sacrifice anything to get a drink. Drinking a glass of wine with dinner or never drinking any alcohol may not necessarily be signs of addiction. Hence, option (a) and (b) are correct.
Step-by-step explanation:
One sign of an addict is craving another drink. This means that the person feels a strong desire or need to consume more alcohol. Another sign is being willing to sacrifice anything to get a drink. This indicates that the person is willing to give up important things to obtain alcohol.
Drinking a glass of wine with dinner, on the other hand, is not necessarily a sign of addiction. Many people consume alcohol in moderation without having an alcohol problem. Lastly, never drinking any alcohol can also be a sign of not being an addict, as it indicates a lack of dependence on or craving for the substance.
