Answer :
C, a headland. Bands of resistant rock along the coastline will be worn away at a slower rate than the softer rock layers either side of it, so a headland (section of land that appears to stick out into the sea when much of the cliff has retreated) is formed.
Answer;
C. headland.
Explanation;
-Headlands form in areas of alternating hard and soft rock. Where the soft rock erodes bays are formed either side of the headland.
-As the headland becomes more exposed to the wind and waves the rate of its erosion increases. When headlands erode they create distinct features such as caves, arches, stacks and stumps.
