A trickster in world mythology is

a) Sedna
b) Loki
c) Amaterasu
d) All of the above

d) All of the above.

The correct answer is b) Loki. Loki is a trickster character in Norse mythology, known for his mischievous nature and cunning abilities. He often plays pranks on the other gods and is a complex, shape-shifting deity. Sedna is an Inuit goddess associated with the sea and marine animals, while Amaterasu is a Shinto goddess of the sun and ruler of the heavens. So, the answer "All of the above" is not correct as Sedna and Amaterasu are not considered trickster figures in world mythology.
