Solution

The correct option is B Arrhythmic
Huntington disease (HD) is a neurodegenerative movement disorder which causes the progressive breakdown (degeneration) of nerve cells in the brain. Huntington's disease has a broad impact on a person's functional abilities characterized by involuntary and irregular movements (Arrhythmic) of the limbs, neck, head, and/or face (chorea).
So, the correct answer is 'Arrhythmic'.
