Best Answer Explained in Below-:

The correct answer to the question is **A) Horizon**. The horizon refers to the apparent line that delineates the earth or sea from the sky. This line is a visual phenomenon that occurs because of the curvature of the Earth; as one looks out into the distance, the ground or water appears to meet the sky at a certain point, creating the horizon.

In contrast, the other options do not apply to this specific context:

- **B) Zenith** refers to the point in the sky directly above an observer, rather than the boundary between the earth and the sky.
- **C) Fringe** generally refers to an outer edge or border of something, which does not conventionally align with the concept of the earth-sea-sky boundary.
- **D) Plinth** is a base or platform upon which a statue or structure is placed, making it irrelevant to the concept of visual limits in the landscape.

Therefore, "horizon" is the term that most precisely describes where the earth or sea visually intersects with the sky, making it the correct choice.
