What is a referendum?

A referendum is a direct vote in which an entire electorate is invited to vote on a particular proposal. This process allows voters to directly decide on important issues, such as constitutional amendments, changes in local laws, or specific policy measures. By involving the electorate in this way, a referendum enhances democratic participation and gives citizens a direct voice in shaping legislation or government decisions.

In contrast to the other options, a referendum specifically focuses on gauging the opinion of the entire eligible voting population on a singular, defined issue, rather than legislative processes, polling, or campaign strategies. Thus, the key characteristic that identifies a referendum is the direct engagement of voters with a specific proposal, making option B the correct choice.
