Final Answer :
E
Explanation :
The scapula's larger size, its protection by muscle, and the clavicle's role as the only bony attachment of the pectoral girdle to the body, along with its positioning making it more likely to be struck, all contribute to why a blow to the shoulder often breaks the clavicle but seldom the scapula.
