Which of the following indicates the speaker's action reflecting personal responsibility?

The action of getting new tires for their car indicates the speaker's personal responsibility because it demonstrates proactive behavior in ensuring the vehicle's safety and functionality. This choice reflects a willingness to address potential issues that could affect not only the speaker but also others on the road. It highlights a commitment to maintaining the car properly, which is a key aspect of responsible vehicle ownership.

In contrast, walking to school does not necessarily relate to personal responsibility regarding vehicle management; it focuses more on commuting choices. Driving recklessly represents a lack of responsibility, as it implies disregard for safety and the well-being of others. Ignoring car problems clearly indicates a failure to take necessary actions to maintain the vehicle and is also a sign of irresponsibility. Therefore, getting new tires is the action that best aligns with reflecting personal responsibility.
