What does it mean to act honorably?

To act honorably means to put honesty and moral principles above all else. This involves making decisions and taking actions that align with ethical values, even when faced with challenges or temptations that may lead one away from such principles. Acting honorably reflects a commitment to integrity and a sense of responsibility towards oneself and others, ensuring that one's actions are guided by a strong moral compass.

This contrasts with the other options, where prioritizing personal gain undermines the essence of honor by disregarding integrity. Behaving in a pleasing manner to others may sometimes align with honorable actions, but it can also involve compromising one's values for the sake of approval. Being prideful about accomplishments can also detract from humility, which is often associated with honor. Thus, the focus on honesty and moral principles encapsulates the true nature of acting honorably.
