Which of the following is a characteristic of Tourette's syndrome?

Tourette's syndrome is a neurological disorder characterized by the presence of multiple motor and vocal tics. Tics are sudden, rapid, recurrent, nonrhythmic motor movements or vocalizations. The presence of multiple tics is a fundamental characteristic of Tourette's syndrome, which often includes a combination of various types of movements or sounds, making the answer reflect the complexity of the disorder.

The sudden jerking of limbs (which can be a form of motor tic) and involuntary grunting (which can be a form of vocal tic) are manifestations of the syndrome. Tics can vary in severity and frequency, and individuals with Tourette's may exhibit a wide range of tics, including both simple and complex movements or sounds. Therefore, since all these attributes can be seen in individuals with Tourette's syndrome, the answer that includes them all captures the essence of the condition effectively.
