Answer
# Brief Explanations:
In hypothesis - testing for independence, the null hypothesis ($H_0$) always states that the two variables are independent, and the alternative hypothesis ($H_A$) states that they are not independent. Here, the two variables are gender and political party. So, the null hypothesis should be that political party is independent of gender, and the alternative hypothesis should be that political party is not independent of gender.
# Answer:
D. $H_0$: Political party is independent of gender.
$H_A$: Political party is not independent of gender.
