The null hypothesis should state that there is no difference in the level of support between male and female voters, so the proportion of support should be equal. Therefore, option A is the correct choice as it assumes that the proportion of support from male voters is equal to the proportion of support from female voters. Option B assumes that the proportion of support from both genders is 50%, which may not always be the case. Option C assumes that the level of support from male and female voters is the exact same as the percentages found in the polls, which may not be true due to sampling errors. Option D is not a valid null hypothesis as it assumes prior knowledge of which group has higher support.
