The process in which rock fragments freeze to the bottom of a glacier and then are carried away when the glacier moves is called a. plucking. b. surging. c. valley widening. d. abrasion.

 a. plucking

Plucking is a glacial phenomena that is responsible for erosion and transfer of rocks in glacier. This occurs in the valley glacier. As a glacier moves down a valley the friction causes the ice present at the base of the valley glacier to melt and the joints of the rocks breaks. Friction has an thawing action on the ice of valley glacier and on the rocks situated at the bottom. Large pieces of rocks come out of ice and gradually they get separated from each other. Loose rocks are carried away by the glacier as it moves.
