In a closed primary, the correct answer is D. Generally, only registered party members may vote.
A closed primary is a type of election where only registered members of a specific political party can participate. This means that voters who have not declared their party affiliation or are not registered with a party do not have the opportunity to vote in the primary election.
To verify this answer, you can examine the rules and regulations of the specific state or district where the primary is taking place. These rules will outline the eligibility requirements for participating in a closed primary election, which typically requires party registration. It's important to consult reliable sources, such as official election websites or government documents, to ensure accurate information.
