Which celebration involves a parade, cultural performances, and local food?

C. Pirates Week is the appropriate choice because it is a vibrant annual celebration in the Cayman Islands that showcases the islands' unique history and culture, particularly their connection to piracy. The event features a lively parade filled with floats and participants in pirate costumes, symbolizing the era of piracy in the Caribbean. Cultural performances, including traditional music and dance, take place throughout the festivities, offering locals and visitors a glimpse into Caymanian heritage. Additionally, a variety of local food vendors come together, providing delicious traditional dishes that reflect the islands' culinary culture. This amalgamation of elements makes Pirates Week a significant and festive occasion that encapsulates the spirit of the Cayman Islands.

The other celebrations listed do not share the same level of festive and widespread community engagement. National Heroes Day is a day to honor the contributions of national heroes, generally marked by more subdued ceremonies rather than large-scale celebrations. Emancipation Day focuses on the history and education surrounding the abolition of slavery in the Cayman Islands, often characterized by reflective events rather than a parade. Earth Day primarily emphasizes environmental awareness and conservation efforts, typically involving community activities like clean-ups rather than cultural festivities.
