According to Zoroastrianism, who represented the evil forces in the world?

I need to know the right answer. Im thinking it was Ahriman but Im not sure

Ahriman

Cambyses

Darius

Ahura Mazda

Angra Mainyu, Aharman, or Ahriman

Ahura Mazda was the source of good.

Angra Mainyu is the Avestan-language name of Zoroastrianism's hypo stasis of the "destructive spirit". The Middle Persian equivalent is Ahriman

Ahura Mazda will ultimately prevail over evil

well, it can't be Aura Mazda cos that is their god, it can't be Darius either cos that is their king.....

Zoroaster taught that Ahura Mazda, the one and only eternal God, created the world as a battleground in which he could meet and overcome the Evil Spirit, Angra Mainyu. The creation was accomplished through his Holy Spirit Spenta Mainyu and the six Holy Imortals (Amesha Spenta), each of whom now dwells in and protects his creation. So the answer is, Angra Mainyu.

Ahriman is evil god of Zarathustra or Zoroaster, he fight Ahuramazda, Cambyses and Darius I,II &III are Shahs, Ahuramazda is good god.

It is from the Zoroastrian religion that the idea of Satan came from to influence later religions
