A Correct answer
Explanation

Venus is the brightest planet in our solar system when viewed from Earth because it has the highest albedo (reflectivity) of all planets due to its thick cloud cover reflecting about 75% of sunlight. Jupiter is actually the most luminous planet overall, but Venus appears brightest from Earth due to its proximity to both the Sun and our planet.
