Answer:

C. is composed of gabbro and basalt overlain by sediment.

Explanation:

The oceanic crust, which extends 5 to 10 kilometers below the ocean floor, is mainly composed of different types of basalts. Below the sediment layer, there is a rocky unit composed mainly of basaltic lavas that contain abundant pillow-shaped structures called padded basalts. The gabbros are in the deepest interior part of the crust.
