Which of the following is a symptom of Hepatitis B?

Dark urine is a recognized symptom of Hepatitis B, along with other indicators such as jaundice (yellowing of the skin and eyes) and fatigue. The presence of dark urine often suggests that there is a higher level of bilirubin in the urine due to the liver's compromised ability to process and excrete it, which is a direct consequence of liver inflammation or damage caused by the Hepatitis B virus.

While loss of taste, muscle cramps, and skin rashes can be associated with various health conditions, they are not specifically indicative of Hepatitis B. The primary symptoms related to Hepatitis B focus significantly on liver function and related changes, making dark urine a more relevant symptom to this particular illness.
