Answer 2

The International Astronomical Union (IAU) defines a constellation by its boundary. The correct option is A.

What is International Astronomical Union?

In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.

The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.

The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.

Thus, the correct option is A.
