Correct Option: D. Integrity Explanation of Why the Answer is Correct: The quotation emphasizes several key aspects of moral character: being truthful to oneself, being truthful to others, being trustworthy, and doing what is right regardless of circumstances. These elements collectively define integrity.

1. Being Truthful to Oneself: This means having self-honesty and being aware of one’s own values, beliefs, and actions. Integrity requires that individuals are true to their own principles and do not deceive themselves about their motivations or behaviors.
2. Being Truthful to Others: This aspect highlights the importance of honesty in relationships. Integrity involves being open and truthful in interactions with others, fostering trust and respect.
3. Being Someone Others Can Trust: Trustworthiness is a cornerstone of integrity. When a person consistently acts with integrity, they build a reputation for reliability and honesty, making them someone others can depend on.
4. Doing What is Right Regardless of the Circumstances: Integrity is about adhering to moral and ethical principles even when it is difficult or when no one is watching. This commitment to doing the right thing, regardless of external pressures or consequences, is a hallmark of a person with integrity.

Why the Other Options are Wrong or Weaker:

• A. Selflessness: While selflessness involves putting others' needs before one's own, it does not necessarily encompass the broader concept of integrity. A selfless person may act out of compassion but may not always be truthful or trustworthy. Integrity includes selflessness but also requires honesty and moral consistency.
• B. Diligence: Diligence refers to careful and persistent work or effort. While a diligent person may be hardworking and committed, this does not inherently include the moral dimensions of truthfulness and trustworthiness that define integrity. Diligence is more about work ethic than moral character.
• C. Discipline: Discipline involves self-control and the ability to follow rules or standards. While discipline is important for personal development and achieving goals, it does not directly address the moral aspects of being truthful and trustworthy. A disciplined person may still lack integrity if they are not honest or ethical in their actions.

Summary of Key Points:

• Integrity is defined by honesty to oneself and others, trustworthiness, and moral consistency.
• The quotation highlights the essential qualities of integrity, making it the most fitting option.
• Other options like selflessness, diligence, and discipline, while valuable traits, do not encompass the full moral scope of integrity.
• Understanding integrity is crucial for personal development and building trustworthy relationships in civic life.
