What information is indicated on a challenger's badge?

A challenger's badge is specifically designed to identify the individual’s role in the voting process as it pertains to election integrity. The correct information indicated on the badge is the candidate or political party they represent. This is crucial because challengers are appointed by candidates or political parties to observe the electoral process, and their affiliation must be clear to ensure transparency and maintain the integrity of the election. By displaying this information, it allows election officials and other observers to understand the political interests that the challenger is advocating for during the voting process.

In contrast, the other options do not accurately reflect the purpose of the badge. While a voter's name or the election date may be relevant to the broader voting process, they do not pertain to a challenger's specific role or authority. Similarly, indicating whether someone is a challenger or an observer does not specifically provide the necessary context surrounding the political affiliations and objectives that the challenger is engaging with during the election.
