Which of the following lists the correct number of principal meridians?

• A. 32 principal meridians
• B. 24 principal meridians
• C. 40 principal meridians
• D. 36 principal meridians

Answer: (D)

Think of principal meridians as the main network of channels that this exam system uses for clinical reasoning. In this material, that network is counted as 36 channels, a broader set than the twelve primary channels alone because it includes additional channels that are treated as principal within this framework due to their regular clinical relevance and clear pathways.

This makes the option with 36 the best choice because it matches the catalog of principal meridians defined by this course. The other numbers correspond to different groupings or classifications in other traditions or texts, not the set being tested here. So 36 aligns with the material’s standard listing.
