Anatomy Chest Wall Anatomy

A 40-yr-old man is brought to the ER because of 1 hour of SOB and sharp pain in the chest wall. He was playing basketball and received an elbow blow to the chest. A chest X ray shows fracture of the 6th rib and right sided pneumothorax. A chest tube is inserted to drain the pleural air. Based on the CT scan below, the chest tube was most likely inserted through which of the following muscles?

A) Pectoralis major
B) Rhomboideus major
C) Serratus anterior
D) Teres major

I know that A is wrong.

It's obvious from the position of CT it's Serratus Anterior
