Which constellation is home to the brightest star, Sirius?

Sirius, often referred to as the Dog Star, is indeed located in the constellation Canis Major, which is not one of the provided options. However, the confusion may arise because Canis Minor (one of the choices) is also a dog-related constellation but does not contain Sirius.

Sirius is the brightest star in the night sky and is part of the Canis Major constellation, which is directly associated with Canis Minor in mythology as both represent dogs in the context of the hunt. Canis Major, along with Canis Minor, connects to the larger tradition of depicting hunting dogs in the sky, emphasizing their proximity and association.

The other options, such as Bootes, Cancer, and Virgo, do not contain Sirius and are not associated with this significant star in astronomical observations.
