What forms first in the retreat process of a sea cliff?
Answer and explanation
Correct answer: Wave-cut notch
At the beginning of sea-cliff retreat, waves attack the weakest zone at the foot of the cliff and excavate a wave-cut notch. Continued hydraulic action and abrasion enlarge this hollow; the unsupported rock above then collapses, causing the cliff line to move landward. Thus option B identifies the first feature, whereas the other options are glacial, karst, and wind-related landforms.
