What type of Judaism did Tzadok create as a result of his misunderstanding?

The choice that correctly refers to the movement associated with Tzadok is Sadduceeism. Tzadok was a high priest during the time of the Second Temple who rejected certain interpretations of Jewish law and the Oral Torah, leading to the formation of the Sadducee sect. The Sadducees specifically contended with the Pharisees, who upheld the Oral Law alongside the Written Torah.

Sadduceeism is characterized by its strict adherence to the written Torah and the denial of certain beliefs held by the Pharisees, such as the resurrection of the dead and the existence of an afterlife. This misunderstanding and subsequent rejection of elements central to Rabbinic Judaism were pivotal in forming a distinct theological and social community during the Second Temple period.

The other options mentioned do not accurately represent this historical figure or movement. Tzaddikism is not a recognized sect related to Tzadok, and Rabbinic Judaism developed later in response to the fall of the Second Temple and the decline of Sadducee power. Meanwhile, “Tzadookis” isn't a term used in historical texts relating to Tzadok or his followers. Thus, Sadduceeism remains the appropriate term for the movement Tzadok established due to his misunderstanding
