Solution

The correct option is D Arrhythmic
Huntington's chorea is a devastating, hereditary, degenerative brain disorder. As the disease progresses, concentration and short-term memory diminish and involuntary movements of the head, trunk and limbs increase. Limb movements become arrhythmic.
Thus, the correct answer is the option B.
