Please help it’s timed and i don’t have that much time left

I'm thinking D because b and c are saying the same thing basically and A is accurate but it doesn't go to well with the question good luck

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

thats not even an aswer choice
