Which reef is the youngest?

I'm curious to know, among the vast array of reefs found throughout the world's oceans, which one can be considered the youngest? Is it a newly formed reef in a remote corner of the Pacific, or perhaps a lesser-known gem nestled in the waters of the Indian Ocean? I'm eager to learn more about this youthful reef and the unique characteristics that set it apart from its more established counterparts. What makes it stand out as the youngest reef in our vast oceanic realm?
