Answer: (B)

Cachexia in the context of HIV/AIDS refers to a complex syndrome characterized by significant weight loss, muscle wasting, and a decline in physical function that is not fully reversible by normal nutrition. It is commonly associated with chronic illnesses, including HIV/AIDS, and arises due to a combination of factors such as inflammation, decreased appetite, and metabolic changes. In patients with HIV/AIDS, cachexia can severely impact quality of life and overall health, making it an important consideration in the management of the disease. Recognizing and addressing cachexia is crucial for improving patient outcomes and providing comprehensive care.
