Explanation:

- Option 1: Uncontrolled movements or muscle stiffness

- Wilson's disease can cause neurological symptoms like tremors, muscle stiffness, and uncontrolled movements due to copper accumulation in the brain.

- Option 2: Problems with speech, swallowing or physical coordination

- Speech difficulties and coordination issues are common symptoms as the disease affects the nervous system.

- Option 3: Fluid build-up in the legs or abdomen

- This is related to liver dysfunction, a key symptom of Wilson's disease, resulting from the body's inability to effectively process copper.

- Option 4: Night blindness

- Night blindness is typically associated with vitamin A deficiency or retinitis pigmentosa, not Wilson's disease.

Option 4: Night blindness is not a symptom of Wilson's disease.
