Final answer:
The correct answer is option b) The Nymphs.
Step-by-step explanation:
The daughters of Nereus and Doris who lived in the sea and assisted sailors were the Nereids, sea nymphs in Greek mythology. These mythological figures were said to have 50 daughters, all of whom represented the sea's friendly and benevolent aspects. The Nereids were often depicted as beautiful maidens who were compassionate towards humans and could either assist sailors or bring calm seas.
According to the mythology, when Queen Cassiopeia compared her beauty to that of the Nereids, she offended Poseidon, the god of the sea. Poseidon, taking grave offense at this comparison, summoned a sea monster named Cetus to ravage the kingdom as retribution. King Cepheus, husband of Cassiopeia, was advised by an oracle to sacrifice their daughter Andromeda to appease the sea monster. The Nereids thus play a significant role in this legend, displaying the power and esteem of these mythological sea denizens.
