Which point clears heat, regulates the Governing vessel, and is used for malaria?

The correct answer is based on the properties and clinical applications of the acupoint in question. DU-13 (Taodao) is recognized for its ability to clear heat and is specifically indicated for conditions like malaria, which is characterized by heat signs, such as fever and chills. Additionally, this point helps regulate the Governing vessel, an important pathway in Traditional Chinese Medicine that influences the body's overall governance and balance.

DU-13 is located on the back of the neck, and its stimulation can aid in dispelling pathogenic factors, particularly those that present with febrile conditions. By clearing heat from the body, it addresses symptoms related to malaria effectively. This makes it a valuable point for practitioners when dealing with cases that require both heat-clearing and regulation of the Governing vessel's functions.

The other points listed have different actions or focuses and may not specifically address the conditions associated with malaria and heat clearing as effectively as DU-13 does. Hence, DU-13 is the most appropriate choice for these therapeutic goals.
