In “cruel tribute,” which character’s actions most advance the development of the plot?

Theseus.

Explanation:

In "Cruel Tribute", King Minos of Crete had imposed a tribute of seven maidens and seven young men on Athens. This was his way of exacting revenge on the killing of his son Androgeos, who he claimed was killed by the Athenian King Aegeus. Thesues is the new found son of King Aegeus, who had volunteered to be part of the tribute to be sent to King Minos. His character's actions of fighting the Minotaur in the cave, and the subsequent following by Ariadne, the Princess of Crete all led to the development of the plot.
