Answer:
The correct answer is B. The difference between open and closed primary elections is that open primaries allow any voters to participate, while closed primaries are restricted to party members.
Step-by-step explanation:
A primary election is an election in which voters under a determinated jurisdiction select the candidate that a party will present to a later public election. In other words, it is a democratic way of pre-selecting the candidate that a party will present to a certain electoral process.
In closed primaries, only registered members in the party can vote, but not the independent electors. On the other hand, in open primaries a registered voter can vote in any primary of any party regardless of their political affiliation.
