What celestial body may sometimes be observed in daylight?

A New Moon
B Saturn
C Venus
D Sirius
AI Explanation

The correct answer is C) Venus. Venus is the only planet that can sometimes be observed in daylight. This is because Venus is the second-closest planet to the Sun, and it reflects a significant amount of sunlight, making it bright enough to be visible in the daytime sky, especially when it is at its greatest elongation from the Sun. The other options are incorrect because the New Moon is not visible at all, Saturn and Sirius are not bright enough to be seen during the day.
