The correct answer is option 2: a person cannot contest an election from more than two constituencies. This means that a person can only run as a candidate in a maximum of two different constituencies for a single election. This rule is in place to prevent individuals from spreading themselves too thin and possibly not being able to effectively represent their constituents if elected. It also allows for a more fair and balanced representation, as candidates can only focus on a limited number of areas and their specific needs. Contesting elections from multiple constituencies can be challenging and demanding, so setting a limit helps ensure that candidates are able to devote enough time and resources to each constituency they are running in.
