Correct Option B - Serratus anterior:

Serratus anterior: The serratus anterior muscle is primarily responsible for stabilizing the scapula against the thoracic wall. When the serratus anterior muscle is paralyzed or weakened, it can lead to winging of the scapula. This muscle is especially important for maintaining proper scapular position during movements such as pushing, pulling, and reaching.
