Answer:
D. Only voters who are registered members of a party can vote in a closed primary, while independent voters can vote in open primaries.
Step-by-step explanation:
Option D is correct because in primaries there are closed and open primaries. In closed (also known as partisan), it allows only declared party members (registered members) to vote.
Whereas in open primaries (nonpartisan) all voters are enabled to choose which party’s primary they wish to vote (they are independent voters).
Primaries may also be direct or indirect primary.
