Answer :

To determine the percentage of female drinkers who could be diagnosed as alcohol dependent, we should consider general knowledge and statistical data from public health studies and reports.

### Step-by-Step Analysis:

1. Understanding Alcohol Dependence:
- Alcohol dependence is characterized by an inability to control drinking due to both a physical and emotional reliance on alcohol.

2. General Epidemiological Data:
- Studies from health institutions such as the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the World Health Organization (WHO) provide data on alcohol dependence among different demographics.

3. Statistical Estimates:
- Data from these studies suggest that the overall prevalence of alcohol dependence in the general population is typically lower than people might expect.
- Among adults in the United States, for instance, studies have shown that roughly 6-8% of individuals may be diagnosed with alcohol use disorder, with a portion of these being cases of alcohol dependence.

4. Gender-Specific Data:
- When zeroing in on female drinkers specifically, the percentage tends to be lower than that of males due to generally lower rates of heavy drinking.
- Nevertheless, a significant minority of female drinkers can have alcohol dependence.

5. Comparing the Options:
- 0-1% (Option a): This is likely too low, given the overall percentages for alcohol dependence.
- 3-5% (Option b): This can be plausible for certain studies, though it usually aligns more with general alcohol use disorder rather than specific dependence.
- 15-20% (Option c): This appears quite high for female drinkers specifically, as it would imply a substantial portion of the population.
- 30-45% (Option d): This range seems particularly high and less likely in a general population context.

Based on general public health data and the prevalence of alcohol dependence among female drinkers, Option b (3-5%) appears to be the most accurate and reasonable estimate.

Therefore, the correct option is:

b) 3-5%
