Plz help I don't understand

hello there,

guys i’m confused.

which rock will weather faster?

answer: b rock

i think its c. amphipod

i believe the answer would be b. hope it : )

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers

hope it ,
