The correct answer is B. A constellation is defined as a group of stars that appear to form a pattern in the night sky as seen from Earth. The stars within a constellation are typically at vastly different distances from Earth and are not physically related to each other; their apparent pattern is merely a line-of-sight effect from our perspective.
A constellation is an apparent pattern of stars in the sky, where the constituent stars are generally not equidistant from Earth.
