Final answer:
In Traditional Chinese Medicine, the Lung (LU) meridian is associated with Autumn. This correlation is due to the increased activity of the Lung meridian and its connection to the metal element, which complements the seasonal themes of releasing and introspection. So, the correct answer is b. LU - Lung Meridian.
Step-by-step explanation:
The meridian associated with Autumn in the context of Traditional Chinese Medicine (TCM) is the Lung (LU) meridian.
Each season in TCM is associated with different meridians that can affect the body's Qi, or vital energy.
During Autumn, it is believed that the Lung meridian becomes more active as Lung energy correlates with the metal element, which is also associated with this season.
Moreover, the Lungs are considered to be the organ responsible for respiratory functions, which align with themes of Autumn such as letting go and introspection, paralleling the falling leaves.
So, the correct answer is b. LU - Lung Meridian.
