b. once - living organisms under pressure for many years
c. small grains of sand getting pressed together over time
d. sedimentation of layers at the bottom of a body of water

Explanation:

The rock in the image appears to be a sedimentary rock. Sedimentary rocks can form from the sedimentation of layers at the bottom of a body of water (D) and small grains of sand getting pressed together over time (C). Option A is for igneous rocks, and option B is more related to some specific types of sedimentary rocks (like coal from plant material) but not as general as C and D for sedimentary rock formation in general.

Answer:

C. Small grains of sand getting pressed together over time, D. Sedimentation of layers at the bottom of a body of water
