Which of the following best illustrates 'respect'?

Acknowledging someone's achievements is the best illustration of 'respect' because it demonstrates an appreciation for the efforts and successes of others. This action validates the individual's hard work and contributions, fostering a sense of value and worthiness. By recognizing and celebrating someone’s accomplishments, it shows that you hold them in high regard and appreciate their efforts, which is a fundamental aspect of respect.

In contrast, ignoring someone entirely conveys a lack of interest or consideration, which goes against the principle of respect. Making fun of someone's mistakes can be harmful and derogatory, undermining their dignity and self-esteem. Finally, taking credit for another's work is an act of dishonesty that disrespects the original contributor's efforts, undermining the foundation of respect based on honesty and integrity in relationships. Thus, acknowledging achievements aligns perfectly with the core values of respect.
