Which of the Following Statements Distinguishes the Tremor and Dysmetria

Which of the following statements distinguishes the tremor and dysmetria typical of cerebellar disorders?

A) Dysmetria is difficulty with performing rapid alternating movements,whereas tremor is impairment in measuring the distance of muscular acts (overreaching or underreaching)
B) Dysmetria is impairment in measuring the distance of muscular acts (overreaching or underreaching) ,whereas tremor is an involuntary,rhythmic,oscillatory movement of a body part seen during movement toward the target
C) Cerebellar tremor is difficulty with performing rapid alternating movements,whereas dysmetria is impairment in measuring the distance of muscular acts (overreaching or underreaching)
D) Cerebellar tremor is involuntary,rhythmic,oscillatory movement of a body part typically seen at rest,whereas dysmetria is impairment in measuring the distance of muscular acts (overreaching or underreaching)
