Answer : 2. "समुद्र भृगु (सी क्लिफ़) "
Explanation :

A sea cliff refers to a steep rocky coast that rises almost vertically above the seawater. Sea cliffs are typically formed by the erosive action of waves over a long period of time, causing the coastline to retreat inland and leaving behind a vertical or near-vertical rock face. These formations are often found in areas with rugged coastlines and are a result of various geological processes and erosion by the sea. Sea cliffs can be impressive natural landmarks and are often admired for their dramatic and picturesque views.
