Final answer:
Voting in an election is an example of a civic life activity, representing an important civic responsibility and a key part of political engagement.
Step-by-step explanation:
Civic life pertains to the activities that citizens participate in to be involved in the democratic process and to fulfill their civic responsibilities or duties to the community or society. These activities typically include being informed, engaging in discussions about civic issues, voting, serving in public office, volunteering in political campaigns, and more.
Out of the options given, voting in an election is a primary example of civic life activity. It represents an essential duty and right as part of one's political responsibilities and is a direct way for citizens to have their voices heard in government decision-making processes.
Other activities like cleaning the backyard, going to work, and paying bills are important tasks in everyday life, but they don't usually constitute civic engagement in the political or community-oriented sense.
