Final answer:

The external and internal intercostal muscles perform rib elevation.

Step-by-step explanation:

The muscles that perform rib elevation are the external intercostal muscles and the internal intercostal muscles.

The external intercostal muscles raise the rib cage during inspiration, while the internal intercostal muscles draw the ribs together to constrict the rib cage during expiration.
