The correct answer is option 1, which states that coastal erosional features include the notch, sea arch, and cliff.

1. Notch: A notch is a narrow indentation or cut into a coastline. It is formed through the erosional action of waves and can often be found at the base of cliffs or headlands.

2. Sea Arch: A sea arch is a natural rock formation that is created when waves erode a cave in a headland or cliff, eventually leading to the formation of an arch. Over time, the arch may collapse, leaving a stack or isolated pillar as a remnant.

3. Cliff: A cliff is a vertical or near-vertical rock exposure on a coast that has been formed by erosion. Cliffs are commonly found on coasts where the land is being eroded by the action of waves or other natural processes.

4. Hook: A hook is not a coastal erosional feature. It is a coastal landform that usually occurs as a result of deposition. A hook is a curved spit or bar that extends from a coast in an arc shape, often forming a sheltered bay or lagoon behind it.

In conclusion, options 2, 3, and 4 are not correctly identified as coastal erosional features.
