Which definition best describes accountability?

The definition that best describes accountability is centered around the concept of being responsible for one's actions and decisions. Accountability implies that an individual is expected to take ownership of their duties and the outcomes of their behavior. This encapsulates a sense of responsibility where one must answer for their performance and the consequences that arise from it.

The other options provide related concepts but do not capture the essence of accountability as effectively. For example, influencing others may be a characteristic of a leader, but it does not inherently involve being answerable for one's actions. Leading a team also suggests a role of authority and guidance, yet it does not encompass the specific idea of being responsible for results. Similarly, efficiency refers to how well resources are used to achieve a goal, which is a different aspect of performance that does not directly relate to accountability. Thus, the focus on responsibility makes the chosen definition the most accurate representation of what accountability entails.
