Final answer:
In Greco-Roman mythology, Demeter is not one of the Fates; she is the goddess of the harvest and fertility. The Fates includes the Clotho, Lachesis, and Atropos. Option D is correct.
Step-by-step explanation:
The student is inquiring about the identities of the three Fates in Greco-Roman mythology. The three Fates are Clotho, who spins the thread of life; Lachesis, who measures the thread of life; and Atropos, who cuts the thread of life, thereby determining an individual's moment of death.
Demeter, on the other hand, is the goddess of the harvest and fertility and is not one of the Fates. Therefore, the correct answer to which of the options is NOT one of the Fates is D) Demeter.
