The correct answer is

Moon

Moon is correct.

The Moon is the brightest object in the night sky, with an apparent magnitude of about −12.7 at full moon.

It has no light of its own; it shines by reflecting sunlight, and it looks so bright because it is very close to Earth, only about 3.84 lakh km away.

Jupiter (about −2.9) and Mars (up to about −2.9) are far fainter, and the brightest star, Sirius, is only about −1.46. Among planets, Venus is the brightest, but it is still much dimmer than the Moon.
