Which of the following best describes Tina's alcohol consumption pattern?

Tina's alcohol consumption pattern is best described as mild social drinking because this indicates an occasional and moderate approach to alcohol use, typically in social settings. Social drinkers do not consume excessive amounts of alcohol regularly, and their drinking does not interfere with daily life or responsibilities.

The other options suggest patterns that are either more problematic or less frequent than what is indicated for Tina. Daily heavy drinking implies a regular and excessive intake that can lead to addiction and health issues, which doesn't align with a mild social drinking pattern. Irregular binge drinking involves episodes of consuming large quantities of alcohol in a short period, suggesting a more harmful and risky behavior than what is described for Tina. Long periods of abstinence would indicate that she does not drink alcohol at all for significant times, which contradicts the notion of moderate social drinking. Thus, mild social drinking accurately captures Tina's relationship with alcohol.
