A motor symptom commonly observed in early Huntington's disease is:

Explanation:
Early Huntington's disease is dominated by chorea, a pattern of quick, involuntary, irregular movements that often involves the face. Grimacing and poor facial control are classic facial manifestations of these choreiform movements, so that option best fits an early motor symptom. General weakness is nonspecific, psychiatric changes are non-motor, and tremor in the limbs is not typical of Huntington's chorea—tremor is more characteristic of other conditions.
