Final answer:
The island sacred to Aphrodite is Cyprus, where she is believed to have emerged from the sea foam.
Step-by-step explanation:
The island that is sacred to Aphrodite is none other than Cyprus. Aphrodite is a mythological figure known as the goddess of love, beauty, and desire in ancient Greek mythology. According to the myths, she was born from the sea foam near Cyprus, and as a result, the island holds a significant place in her worship and mythos. While other options like Crete and Rhodes have their own historical and mythological importance, with Crete being the center of the Minoan civilization and Rhodes being associated with the sun god Helios, Cyprus holds the unique distinction of being intimately connected with Aphrodite.
