The alternative hypothesis for a proportion test should specify a different value than the null hypothesis, indicating whether the proportion is greater than, less than, or not equal to a specified value. Option A correctly specifies that the population proportion is less than the null hypothesis value of 0.65, making it an appropriate alternative hypothesis. The other options either specify the sample proportion or an equality with the null hypothesis value, which are not appropriate alternative hypotheses.
