the core
the photosphere
the corona
the radioactive zone
rewatch

Explanation:

In solar physics (a subfield of Physics, under Natural Science), the photosphere is considered the Sun’s visible surface. The core is the Sun’s central region for fusion, the corona is the Sun’s outer atmosphere (visible during eclipses), and the "radioactive zone" (likely a typo for "radiative zone") is an internal layer for energy transfer. So the photosphere is the Sun’s surface - like layer we observe.

Answer:

The photosphere (the option "The photosphere")
