B Correct answer
Explanation

Venus appears brightest in Earth's sky because it has the highest albedo (reflectivity) of all planets and comes closer to Earth than any other planet. Jupiter is actually the largest planet but appears dimmer from Earth due to its greater distance.

AI explanation

Venus is the brightest planet as seen from Earth because it is covered in thick, highly reflective clouds of sulfuric acid that bounce back a large fraction of incoming sunlight, and it also orbits relatively close to both the Sun and Earth. This high reflectivity (albedo) makes it outshine every other planet in the night sky. Mars and Jupiter are dimmer despite Jupiter's large size, since size alone doesn't determine apparent brightness.
