A. reticular formation
B. association cortex
C. motor cortex
D. limbic system

C. primary motor cortex

Explanation:

Due to the ability of the brain to reorganize itself through the formation of new neural connection throughout life, the primary motor cortex of players of musical instrument such as violin, cello, and viola is largely devoted to the hands of these players. The role of the primary motor cortex is for the generation of impulses that control movement execution.
