Answer:
A. supplementary motor cortex; premotor cortex
Explanation:
The supplementary motor cortex, also known as the supplementary motor area (SMA), is an area of the cerebral cortex located anterior to the premotor cortex. This area (SMA) is involved in the execution of complex and rapid sequential movements (e.g., typing). Moreover, the premotor cortex is an area of the motor cortex located between the primary motor cortex and the prefrontal cortex. This area (premotor cortex) is activated during motor tasks including, among others, spatial and sensory guidance of movement.
