Final Answer :
E
Explanation :
The zygomaticus major and minor muscles are responsible for raising the corners of the mouth for smiling and laughing. The buccinator muscle helps with the movement of the cheeks, the mentalis and platysma muscles aid with movements of the chin and lower lip, and the depressor anguli oris muscle aids in lowering the corners of the mouth. The orbicularis oris muscle is responsible for puckering the lips.
