Correct answer: D — Essential tremor

An action tremor with family history and no parkinsonian signs is most consistent with essential tremor. Parkinson's disease typically has bradykinesia and often a resting, asymmetric tremor. Examination for rigidity and bradykinesia is crucial before labelling a tremor as Parkinson's disease.
