The correct answer is เพลงงามแสงเดือน because it is a traditional folk song that is commonly performed in various cultural events and festivals. It is considered a standard and well-known song in the repertoire of Thai folk music. The other options, เพลงลอยกระทง, เพลงรำอวยพร, and เพลงปีใหม่, are also traditional songs but they are not as widely recognized or performed as เพลงงามแสงเดือน.
