Final answer:
The ultimate responsibility for an action lies with the person who performs it, known as personal responsibility.
Step-by-step explanation:
The principle that the ultimate responsibility for an action lies with the person who performs it is known as personal responsibility. Personal responsibility means that individuals are accountable for their choices and the consequences that result from those choices.
For example, if a student chooses to skip studying for a test and instead goes to a party, they are responsible for the potential consequences, such as receiving a failing grade. Personal responsibility extends to all aspects of life, including work, relationships, and personal goals.
By understanding personal responsibility, individuals are empowered to make informed decisions and take ownership of their actions.
