A) internal oblique
B) external oblique
C) transversus abdominis
D) rectus abdominis
E) All of the answers are correct.

Accepted Answer

All of the listed muscles are capable of compressing the abdomen.

The rectus abdominis also contributes to intra-abdominal pressure and assists with forced expiration.
