A: the congress, the council, and the assembly

The three main parts of Athenian Democratic government were A: the congress, the council, and the assembly.

To determine the correct answer, let's break down the question and understand the key terms involved.

The question asks about the three main parts of Athenian Democratic government. This implies that we need to identify the fundamental institutions or bodies that constituted the democratic system in Athens.

Let's examine the answer choices:

A: the congress, the council, and the assembly
B: the house of representatives, the president, and the assembly
C: the assembly, the courts and president
D: the assembly, the courts, and the council

A: The term "congress" is not typically associated with Athenian democracy. The council and assembly were indeed important components.
B: The terms "house of representatives" and "president" generally refer to government structures in contemporary contexts, not to Athenian democracy.
C: The answer choice includes the assembly, which aligns with what we expect, but the term "courts and president" is not accurate.
D: This answer includes the assembly and courts, which are known features of Athenian democracy. The inclusion of the council in this option is also correct.

Based on this analysis, the correct answer is option D: the assembly, the courts, and the council. These three components formed the primary parts of Athenian Democratic government.
