PLEASE HELP! ALSO PLEASE DO NOT ANSWER WITH "IDK" OR ANYTHING LIKE THAT!! Read the following passage from "The Golden Fleece" in Bulfinch's Mythology.

When Jason was grown up and came to demand the crown from his uncle, Pelias pretended to be willing to yield it, but at the same time suggested to the young man the glorious adventure of going in quest of the golden fleece, which it was well known was in the kingdom of Colchis, and was, as Pelias pretended, the rightful property of their family.
What is the most likely reason Pelias sent Jason on this "pretend" mission?

it was a long-standing family tradition that before a son could rule, he must embark on a dangerous quest.
Pelias hoped that Jason would be killed on the quest and that he (Pelias) could continue to be king.
Pelias really wanted the golden fleece and thought Jason could get it.
Pelias wanted Jason to earn the right to rule as king by completing a quest.
