Which of the following is not an obligation of a citizen?

The obligation of a citizen refers to the duties or responsibilities that a person must fulfill as a member of a community or country. Out of the given options, attending religious gatherings is not an obligation of a citizen. While freedom of religion is a fundamental right in many countries, attending religious gatherings is a personal choice and not mandatory. It is not a duty that is required of citizens by law or by the government. On the other hand, payment of taxes is necessary to fund public services and infrastructure that benefit the community. Voting in elections is a civic duty that allows citizens to have a say in their government and choose their representatives. Protecting public property is also a responsibility that citizens must fulfill to ensure the safety and security of their community.
