Which of the following best exemplifies sympathy?

The choice that best exemplifies sympathy is expressing sincere concern for a grieving person. Sympathy involves recognizing the feelings of others and conveying compassion and support during difficult times. This emotional connection helps to comfort the grieving individual, showing that you acknowledge their pain and are there to support them in their sorrow.

Sharing personal experiences, while sometimes well-intentioned, can divert the focus from the grieving person's feelings and may come off as self-centered. Dismissing the feelings of others does the opposite of fostering connection and understanding, as it negates the grief they are experiencing. Offering financial assistance, while generous and potentially very helpful, is more of a practical action and does not inherently communicate emotional concern or understanding of the grieving person’s emotional state. Sympathy is primarily about emotional support and connection, making the expression of sincere concern the most appropriate choice.
