The fastival of the sun is held on June 24th. A.celebrated B.performed C.attended D.paraded

The correct answer is A. celebrated.

The reason for this is that "celebrated" is the term that typically refers to a special event or occasion that is acknowledged or recognized with festivities, ceremonies, or gatherings. In the context of a festival, people come together to honor or mark the significance of the occasion.

On the other hand:

- "performed" suggests carrying out an activity, typically in front of an audience, like a play or a concert, which doesn't fully capture the essence of how a festival is experienced by communities.
- "attended" refers to the act of being present at an event, but it does not convey the idea of actively partaking in the festivities or recognizing the importance of the event.
- "paraded" implies a public procession, which might be part of a festival but doesn't capture the overall concept of celebrating the festival itself.

Therefore, when discussing the festival of the sun specifically and how it is recognized or acknowledged, "celebrated" is the most appropriate choice.
